FOCUS AND WH-FEATURES IN INTERROGATIVE C *Kensuke Takita
Nanzan University

1. Introduction
In Japanese, word order is relatively free. For example, both SOV and OSV orders are
possible, as shown in (1).
(1) a. Taroo-ga
-Nom

hon-o
book-Acc

kat-tabuy-Past‘Taroo bought a book.’b. Honi-obook-Acc

Taroo-ga-Nomti

kat-tabuy-Past‘Taroo bought a book.’
The OSV order in (1b) is derived by scrambling (see Saito 1985, among others) of the object
to the sentence initial position without changing the meaning of the sentence. Thus, it is
widely assumed that scrambling is not feature-driven, so that it applies freely (see Saito 1985,
1989, Fukui 1986, Kuroda 1988, Saito and Fukui 1998 among many others).1
Besides this optionality, one of the most remarkable properties of scrambling is thatscrambling undergoes “LF-undoing” (Saito 1989), or “radical reconstruction.” Saito (1989)
offers a convincing illustration of the radical reconstruction effect, based on thegeneralization that wh-phrases must be c-commanded by a Q-morpheme (Harada 1972). First,
look at the examples in (2).

Alternatively, Miyagawa (1997, 2001), Kitahara (1997), and Kawamura (2001) argue thatscrambling is in fact feature-driven.

In (2a), the wh-phrase dare ‘who’ is c-commanded by the Q-morpheme ka, and the sentenceis grammatical. On the other hand, in (2b), the wh-phrase is outside of the c-commanddomain of the Q-morpheme. Hence, Harada’s (1972) generalization can correctly rule out theexample in (2b). Then, look at the examples in (3).
(3) a. [TP Taroo-ga [CP [TP Hanako-ga nani-okat-ta]-Nom-Nom what-Acc buy-Pastka] siritagatteir-u]

kat-ta]buy-Pastka] siritagatteir-u]2
Q want-to-know-Pres‘Taroo wants to know what Hanako bought.’
The sentence in (3b) is derived from (3a) by long-distance scrambling of the wh-phrase nani
‘what’ to the matrix clause. Surprisingly, this sentence is grammatical, although the whphrase is not c-commanded by the Q-morpheme at S-structure. Based on this observation,
Saito (1989) argues that the generalization applies at LF and scrambling can be undone at LF,
so that the wh-phrase goes back to its trace position, which the Q-morpheme c-commands.
In this regard, it is expected that there is no restriction on word order alternations inJapanese, as long as they are derived by scrambling. This expectation, however, is not correct.
Look at the contrast found in (4), which is called the “anti-superiority” effect (see A.
Watanabe 1991, S. Watanabe 1994, and Saito 2004, among others).

Saito (1989) attributes the marginal status of (3b) to Subjacency, since the scrambled wh-phrase is
moved out of a wh-island. In any event, what is important here is that there is clear contrast between(2b) and (3b).

naze
why

Taroo-ga-Nomti

kat-tabuy-Pastno?
Q‘Why did Taroo buy what?’
In (4a), naze ‘why’ precedes nani ‘what’, and the sentence is ungrammatical. On the other
hand, in (4b), nani ‘what’ precedes naze ‘why’ as a result of scrambling, and the sentence isgrammatical.3 Given that in-situ wh-phrases moves at LF (Huang 1982), this is unexpectedunder the assumption that scrambling is undone at LF; since radical reconstruction forces theexamples in (4) have the same LF representation, the contrast is left unexplained. Note that
only naze ‘why’ induces the anti-superiority effect; multiple wh-questions are in fact possible
without restriction on ordering.4

3

Given that a subject cannot be scrambled (Saito 1985), the fact that the object wh-phrase nani
‘what’ precedes the subject Taroo ensures that it undergoes scrambling, though we leave the precise
position of naze ‘why’ open at this point.
4

The name “anti-superiority” comes from superiority phenomena. The relevant examples are thefollowing;(i) a.

Whoi ti bought what?

b. * Whati did who buy ti?
(ii) a.

Whyi did John buy what ti?

b. * Whati did John buy ti why?
If the lower wh-phrase moves first, the sentence becomes ungrammatical. Therefore, Chomsky (1973)
proposes the following condition.
(iii) Superiority Condition
No rule can involve X, Y in the structure… X … [α … Z … -WYV …]…
where the rule applies ambiguously to Z and Y and Z is superior to Y.
As we have seen, contrary to the English case which rules out wh-‘why’ order, Japanese allows only
this order. Thus, this phenomenon is called “anti-”superiority. Japanese, however, shows somepeculiar pattern to this condition. Look at the examples in (iv).

Nanzan Linguistics: Special Issue 1, Vol. 1

A similar pattern is found in the following contrast in (5), which is called the intervention
effect by scope bearing elements, henthforth SBEs (see Beck 1996, Beck and Kim 1997).5(5) a. * Hanako-sika
nani-o-only what-Acc

yoma-nakat-ta no?6
read-not-Past Q‘What did only Hanako read?’b. Nanii-owhat-Acc

Hanako-sika
-only

ti

yoma-nakat-ta no?
read-not-Past Q‘What did only Hanako read?’
The contrast in (5) suggests that nani ‘what’ cannot follow the NPI -sika ‘only’. Again, thisword order restriction on SBEs and wh-phrases is not expected, because this word orderalternation is derived by scrambling.
One interesting exception of the intervention effect is the following case, where an SBE
co-occurs with naze ‘why’.
(6) a.

Taroo-ga
-Nom

naze
why

sono
that

hon-sikayoma-nakat-ta no?
book-only read-not-past Q‘Why did Taroo read only that book?’b. Taroo-ga
-Nom

sono
that

hon-sikai nazebook-only whytiyoma-nakat-ta no?
read-not-Past Q‘Why did Taroo read only that book?’
In this case, both of the ‘why’-SBE order and the SBE-‘why’ order are allowed. Note that
only naze ‘why’ can escape the intervention effect. Again, naze ‘why’ shows different
behavior from the other wh-phrases.
The anti-superiority effect, the intervention effect, and the exception of the intervention
effect are schematically summarized as in (7).
These examples indicate that both orders are possible. That is, anti-superiority in Japanese is nottotally opposite to superiority in English. Although the term anti-superiority is a little bit confusing,we continue to use it to refer to the fact that ‘why’-wh order induces ungrammaticality.
5

SBEs include -sika ‘only’, -mo ‘also’, daremo ‘anyone’, dareka ‘someone’, daremo ‘everyone’. In
this paper, we use the Negative Polarity Item (henthforth NPI) -sika ‘only’ because it induces the mostsalient effect.

Ko (2006) illustrates that Korean shows the same pattern of grammaticality with respect to theexamples which this paper provides. Because of the space limitation, we deal with only Japaneseexamples here. We, however, believe that the same explanation holds in the Korean counterparts.

ok[… wh … ‘why’ …] : anti-superiority

Here, three questions arise;(8) a. Why the surface order of wh-phrases and SBEs is crucial to the grammaticality of asentence, given the optionality and the radical reconstruction property of scrambling?
b. Why does naze ‘why’ behave differently from the other wh-phrases?
c. Why do SBEs induce the intervention effect?
Recently, Ko (2005) provides an answer to (8b); she claims that the peculiar behavior of naze
‘why’ with respect to the intervention effect follows from the hypothesis that naze ‘why’ isbase-generated into Spec, CP. Subsequently, Ko (2006) extends the analysis to the antisuperiority effect, assuming the split-CP system (see Rizzi 1997, 1999 especially). In thispaper, however, we show that Ko’s analysis does not make sense if the question in (8a) istaken seriously, because her analysis overlooks the properties of scrambling.
Alternatively, we claim that the ungrammatical cases are ruled out as illicit cases ofvaluation of unvalued features on C. In so doing, we first answer the question in (8b),claiming that naze ‘why’ is different from the other wh-phrases in its feature specification; theordinary wh-phrases have a focus feature whereas naze ‘why’ lacks it. Then, we propose afeature valuation mechanism, which crucially employs Pesetsky and Torrego’s (2004) claimthat valuation of features is independent of interpretability of them, and illustrate how the
proposed mechanism exclude the ungrammatical cases, answering the question in (8c). Moreover, we argue that although the proposed mechanism can provide a partial answer to (8a), it
is necessary to assume Nissenbaum’s (2000) idea that all overt operations precede covert ones
within a certain domain, coupled with Richards’ (2001) tucking-in theory, to give a fullanswer to (8a): On the one hand, Pesetsky and Torrego’s proposal excludes the possibility ofscrambling before feature checking; on the other hand, Nissenbaum’s theory makes
scrambling after covert feature checking impossible because by definition, scrambling is an
overt operation. In addition, tucking-in ensures that overt movement of multiple wh-phrases
to Spec, CP preserves the order of relevant constituents.
This paper is organized as follows. In Section 2, we briefly review the analysis by Ko(2005, 2006) and point out several problems of the analysis. In Section 3, we first recapture
what we have to explain by making a generalization, and briefly argue that the split-CP
system cannot explain the generalization contrary to Ko’s analysis. Then, we provide ananalysis. Section 4 illustrates that the proposed analysis can cover the more complex cases.

Finally, in Section 5, after summarizing this paper, we speculate the status of the Ko’s
hypothesis and the split-CP hypothesis.
2. Previous Analysis and Problems
2.1 CP-Modifier Hypothesis
In this subsection, we review the analysis by Ko (2005) as a first step. First, Ko (2005)
claims that the ungrammatical SBE-wh order can be ruled out by assuming the Intervention
Effect Constraint (Beck and Kim 1997) stated in (9).
(9) Intervention Effect Constraint
At LF, a wh-phrase cannot move across an SBE to its checking (scope) position.
a. *[… Q … SBE … wh …]7
X
b.

ok

[… Q … whi … SBE … ti …](slightly modified from Ko 2006, p.321)

This constraint can rule out the example in (5a). Note that scrambling of the wh-phrase over
the SBE is possible, since scrambling does not involve feature checking. Thus, even if a whphrase is base-generated below an SBE, it can enter the checking relation with Q as long as itis preposed by scrambling, as in (9b).
On the other hand, as we have seen above, naze ‘why’ seems to be exempt from theIntervention Effect Constraint. Ko (2005), however, points out that in some circumstances,
naze ‘why’ is also subject to the Intervention Effect Constraint. Look at the examples in (10).
(10)a. Hanako-ga [CP Taroo-ga
naze
-Nom
-Nom why

kur-uto] it-ta
come-Pres C say-Pastno?
Q‘What is the reason x such that Hanako said that Taroo is coming for x?’
b. * Hanako-sika [CP Taroo-ga naze
-only-Nom why

kur-uto] iwa-nakat-ta
come-Pres C say-not-Pastno?
Q‘What is the reason x such that Hanako said that Taroo is coming for x?’
The example in (10a) indicates that in-situ wh-phrase naze ‘why’ can take matrix scope. In
contrast, if the matrix subject is replaced to the SBE Hanako-sika ‘only Hanako’ as in (10b),
the embedded naze ‘why’ cannot take matrix scope, and the sentence become ungrammatical.
In this case, the example in (10b) has the following LF representation.

Focus and Wh-features in Interrogative C (K. Takita)(11)[CP Q [TP … SBE … [CP … ‘why’ …]]]
X

This structure is straightforwardly ruled out by the Intervention Effect Constraint, since thewh-phrase has to move across the SBE to the matrix interrogative C. Based on this fact, Ko(2005) claims that the exceptional behavior of naze ‘why’ is limited to its clause-internal
movement.
To explain this peculiar property of naze ‘why’, Ko (2005) proposes the following
hypothesis;(12) CP-Modifier Hypothesis‘Why’ in wh-in-situ languages is an adverb that is externally merged in Spec, CP of theclause it modifies.
Under the CP-Modifier Hypothesis (henthforth CMH), the example in (6a), repeated here as(13a), is derived in the manner depicted in (13b).
(13)a. Taroo-ga
-Nom

naze
why

yoma-nakat-ta] no]Step2; Scrambling of the subject to sentence initial position8[CP Tarooi-ga naze [TP ti sono hon-sika
yoma-nakat-ta] no]

Then, the exceptionally grammatical ‘why’-SBE order in (6b), repeated here as in (14a), has
the derivation illustrated in (14b).

Note that contra Saito (1985), scrambling of subject must be possible under the CMH, as argued by
Ko (2005). See Ko (2005, Section 7.1) for the relevant discussion.

b. Step 1; External merge of naze ‘why’ into Spec, CP with feature checking[CP naze [TP Taroo-ga sono hon-sika yoma-nakat-ta] no]
Step 2; Scrambling of the subject and the SBE before naze ‘why’, respectively[CP Tarooi-ga sono hon-sikaj naze
[TP titj yoma-nakat-ta] no]What is crucial here is that scrambling of the SBE takes place after feature checking of naze
‘why’ with Q. Therefore, the SBE does not interfere in the checking relation, as long as naze
‘why’ is merged into an interrogative CP. In this way, Ko (2005) explains the exceptional
behavior of naze ‘why’ with respect to the intervention effect, attributing it to the basegenerated position of naze ‘why’. In other words, Ko (2005) answers to the question in (8b)by claiming only naze ‘why’ can be base-generated into Spec, CP whereas the other whphrases are not.
The anti-superiority effect, however, causes a problem to the analysis. The relevant
example (4a) is repeated as (15).
(15)*Naze Taroo-ga
why
-Nom

nani-owhat-Acc

kat-tabuy-Pastno?
Q‘Why did Taroo buy what?’
The derivation of the example in (15) under the CMH is schematically illustrated in (16).
(16)a. Step 1; Feature checking between the wh-phrase and Q[CP Q [TP … wh …]]

b. Step 2; External merge of naze ‘why’ into Spec, CP with feature checking[CP ‘why’
Q [TP … wh …]

At the Step 1 in (16a), nothing prevents the wh-phrase entering a checking relation with theinterrogative C. Subsequently, ‘why’ is merged into Spec, CP with feature checking. Thus,
the derivation can converge, contrary to the fact.
In addition, Ko herself noticed that her explanation has another problem. Look at theexample in (17a), where the SBE and the wh-phrase precede naze ‘why’.

Focus and Wh-features in Interrogative C (K. Takita)b. [CP SBEi

whj‘why’ Q [TP … ti … tj …]]

As shown in (17b), since the SBE is adjoined to CP, it does not prevent from the wh-phrasefrom entering the checking relation with the interrogative C. Thus, the CMH wrongly rules inthe example in (17a).
To avoid this problem, Ko (2006) adopts Rizzi’s (1999) split-CP system. Rizzi (1999)
claims that CP is a highly structured zone, as shown in (18).

‘why’
wh-movement

Rizzi (1999) also claims that in Italian, perchè ‘why’ is base-generated in Spec, IntP, andSpec, FocP is the landing site for wh-movement. Following his idea, Ko (2006) proposes thatin wh-in-situ languages, there are at least two CP-layers, namely C-Focus (CFoc) and CInterrogative (CInt), where CFoc dominates CInt, as shown in (19).
(19)[CFocP … CFoc [CIntP … CInt [IP …]]↑↑
wh-movement‘why’

Under this revised CMH, the offending example in (17a) has the schematic structure in (20).
(20)[CFocP CFoc [CIntP SBEi
X

whj

‘why’ CInt [IP … ti … tj …]]

Note that in (19), the hierarchical order between CFoc and CInt is reversed from Rizzi’s (1999)
original proposal. Hence, even if naze ‘why’ is merged into Spec, CIntP, as Rizzi (1999)
claims, the wh-phrase has to move to Spec, CFocP, which is located higher than CInt since Spec,
CFocP is the landing site for wh-movement. This movement, however, is impossible since it
crosses the SBE, as shown in (20). Therefore, the revised CMH can correctly rule out the casein (17a).
Given the revised CMH, Ko (2006) extends her analysis to the anti-superiority effect. In
doing so, Ko (2006) claims that ‘why’ in Japanese and Korean is itself an SBE that induces
the intervention effect. Under this analysis, the ungrammatical ‘why’-wh order has theschematic structure in (21a), whereas the grammatical wh-‘why’ order has the structure in(21b).

Nanzan Linguistics: Special Issue 1, Vol. 1b.

ok[CFocP CFoc [CIntP

whi‘why’ CInt [IP … ti …]]]By hypothesis, naze ‘why’ is base-generated in Spec, CIntP in both cases. In the case of (21a),the wh-phrase has to move Spec, CFocP, crossing naze ‘why’, while nothing intervenes
between Spec, CFocP and the wh-phrase in the case of (21b) because of scrambling. Therefore,
the revised CMH, coupled with the assumption that ‘why’ induces the intervention effect, canexplain the anti-superiority effect.
In this subsection, we reviewed the analysis by Ko (2005, 2006) and illustrated how theanalysis explains the paradigm in (7). The next subsection, however, shows that the
explanation faces serious problems when the optionality and the radical reconstruction
property of scrambling are taken into consideration.
2.2 The “Undesirable Scrambling” Problem
Although Ko’s (2005, 2006) explanation seems to cover the paradigm, it overlooks theproperties of scrambling. Recall that her explanation crucially relies on the LF condition to
distinguish the following two representations in (22).
(22)a. *[… Q … SBE … wh …]
X
b.

ok

[… Q … whi … SBE … ti …]

Ko claims that the structure in (22b) is well-formed because the wh-phrase undergoes
scrambling, not wh-movement. At this point, however, recall also that scrambling is subject
to radical reconstruction at LF, as we have seen above. As a result of radical reconstruction,
the representations in (22a) and (22b) become identical, so that both of them are ruled out by
the Intervention Effect Constraint in (9), contrary to her claim.
One might say that radical reconstruction applies as long as it is necessary (e.g., Bošković
and Takahashi 1998 and Sugisaki 2001), so the scrambled wh-phrase in (22b) need not bereconstructed. If this is the case, radical reconstruction ceases to be a problem. Ko’s analysis,
however, faces more serious problem. Look at the schematic derivation in (23).
(23)a. Step 1; Scrambling of the wh-phrase and the SBE9
[CIntP whi
SBEj ‘why’ CInt [IP … ti … tj …]]

9

The order of the SBE and the wh-phrase within IP is irrelevant here, because both of them are
moved by scrambling.

c. Step 3; Scrambling of the SBE to the CFocP-adjoined position[CFocP SBEj CFoc [CIntP
whit’j ‘why’ CInt [IP … ti … tj …]]]

Suppose that both the SBE and the wh-phrase are moved to the CIntP-adjoined positions
respectively, and the wh-phrase occupies the higher position, as shown in (23a). Then at the
point where CFoc is merged, nothing prevents the wh-phrase from entering a checking relation
with CFoc, as in (23b). Finally, at the Step 3 in (23c), the SBE is scrambled to the CFocPadjoined position. If this scrambling is possible, the ungrammatical SBE-wh-‘why’ order canbe wrongly derived. In fact, the example in (24) suggests that SBEs can be scrambled to thisposition, since it can undergo long-distance scrambling to the matrix clause. Given that aderivation proceeds phase-by-phase (Chomsky 2000, 2001), it is necessary to move thescrambled phrase through the highest edge of CP, namely Spec, CFocP.

We call this the “undesirable scrambling” problem, since the free application of scrambling
obscures underlying checking relations.
The same problem arises in the case of the anti-superiority effect. Consider the following
possible derivation in (25).
(25)a. Step 1; External merge of ‘why’ into Spec, CIntP with feature checking[CIntP ‘why’ CInt [IP … wh …]]
b. Step 2; Scrambling of the wh-phrase to the CIntP-adjoined position[CIntP whi [CIntP ‘why’ CInt [IP … ti …]]]
c. Step 3; Merge of the CFoc head, with feature checking of the wh-phrase[CFocP CFoc [CIntP whi [CIntP ‘why’ CInt [IP … ti …]]]]
d. Step 4; Scrambling of ‘why’ to the CFocP-adjoined position[CFocP ‘why’j CFoc [CIntP whi [CIntP tj CInt [IP … ti …]]]]This derivation yields the ‘why’-wh order. Note that the wh-phrase can enters the checking
relation with CFoc since ‘why’ does not intervene at the Step 3 in (25c), and nothing prevents- 139 -

Nanzan Linguistics: Special Issue 1, Vol. 1‘why’ being scrambled to the CFocP-adjoined position at the Step 4 in (25d) because thechecking relation between ‘why’ and CInt has been already established. Thus, theungrammatical ‘why’-wh order is wrongly predicted to be grammatical.
In addition to the undesirable scrambling problem, there is an independent motivation to
cast doubt on Ko’s (2005, 2006) analysis. Recall that her argument is based on theassumption that ‘why’ is subject to the Intervention Effect Constraint. Evidence for thisassumption is (10b), repeated here as (26a).

(Rizzi 1990, p. 83)

The example in (26b), however, suggests that the example in (26a) is ruled out by otherreasons, independently of the Intervention Effect Constraint. The example in (26b) minimallydiffers from (26a) in that the SBE subject in (26a) is replaced to the non-SBE one. The
example in (26b) is ungrammatical because ‘why’ crosses the negative island (Rizzi 1990). A
typical case of the negative island is shown in (26c). That is, the wh-movement of ‘why’ tothe matrix clause is blocked by negation, which is situated between ‘why’ and the matrix
interrogative C. Note that (26a) also has negation between ‘why’ and the matrix interrogative
C. Therefore, we claim that (26a) is ungrammatical because it violates negative island on parwith (26b), not because feature checking of ‘why’ is blocked by the SBE. Thus, there is no
reason to believe that ‘why’ is subject to the Intervention Effect Constraint.
Summarizing this section, we reviewed the analysis by Ko (2005, 2006) and pointed out
the problems it faces. In particular, we argued that since the analysis has no way to forbid
scrambling to the highest CP-adjoined position, it cannot avoid the undesirable scramblingproblem. We also argued that the assumption that ‘why’ also obeys the Intervention Effect
Constraint is not founded.
3. Proposals and Analysis
This section provides an alternative theory which can explain the paradigm in (7),overcoming the problems of the previous studies. First, Section 3.1 recaptures what we haveto explain. Then, in Section 3.2, we propose a theory which crucially employs Pesetsky and
Torrego’s (2004) conception of feature interpretability and feature valuation, and illustrate
how the proposed mechanism explain the paradigm. Finally, in Section 3.3, we show that a- 140 -

Focus and Wh-features in Interrogative C (K. Takita)

residual problem can be solved if Nissenbaum’s (2000) distinction of overt/covert movement
is adopted, coupled with Richards’ (2001) tucking-in theory, arguing that this in turn supports
Nissenbaum’s theory.

One of the things which we have to explain is the generalization on the word orderamong the SBEs, wh-phrases, and ‘why’. In what way is the word order restricted? Look at
the configurations in (27), to which the whole paradigm in (7) is integrated.
(27)a. *[… Q … SBE/‘why’ … wh …] vs. ok[… Q … wh … SBE/‘why’ …]b.

ok[… Q … SBE … ‘why’ …] vs. ok[… Q … ‘why’ … SBE]

Only the order where the SBE or ‘why’ intervenes between Q and wh-phrases is
ungrammatical. Thus, we have the following preliminary generalization in (28).
(28)Generalization on the Word Order (preliminary)
SBE/‘why’ cannot intervene between Q and wh-phrases, while there is no order
restriction between SBEs and ‘why’.
Here, two questions arise.
(29)a. What is the difference between the ordinary wh-phrases and ‘why’?
b. What is the similarity between SBEs and ‘why’?
Note that the questions in (29) are closely related to the questions in (8b) and (8c). Thus, if
we can answer the questions in (29), it provides a key to answer to (8b) and (8c).
We start with the first question in (29a). Our answer is the following; the ordinary whphrases have the focus feature, while ‘why’ lacks it. In general, wh-phrases bear focus. As
shown in (30a), wh-phrases are incompatible with focused items in Italian.
(30)a. * A chi QUESTO hanno ditto (non qualcos’altro)?10(Rizzi 1999, p. 4)‘To whom THIS they said (not something else)?’b. Perchè QUESTO avremmo dovuto dirgli, non qualcos’altro?

(ibid, p. 7)‘Why THIS we should have said to him, not something else?’
Rizzi (1999) explains this fact by claiming that the wh-phrases and the focused items compete
for the only one focus position, namely Spec, CFocP, to check their focus feature. On the other10

The focused items are indicated in capitals.

hand, as shown in (30b), perchè ‘why’ can co-occur with the focused elements. If ‘why’ lacks
the focus feature, as we claim, their co-occurrence is not surprising because they do notcompete for Spec, CFocP.
Another difference between the ordinary wh-phrases and ‘why’ is found in the barebinary combination construction, exemplified in (31).
(31)a. * When Adam?/*What at school?
b. Why Adam?/Why at school?
Among the wh-phrases, only ‘why’ can appear in this construction. Kawamura (2006a, b)
claims that the non-wh part of the construction, namely Adam or at school, bears focus. If thisis correct, the contrast in (31) can be explained essentially in the same way as the explanationof (30) above. That is, given a sentence cannot have double foci, only the examples in (31b)are grammatical since ‘why’ lacks the focus feature.
Finally, another instance of the focus association of ‘why’ can be found in (32).
Bromberger (1992) observes that focus-shift affects the range of possible answers to whyquestions, as shown in (32).
(32)a. Why did ADAM eat the apple?
---Because he was the one that Eve worked on.
b. Why did Adam EAT the apple?
---Because he couldn’t think of anything else to do with it.
c. Why did Adam eat the APPLE?
---Because it was the only food around.
The examples in (32) indicate that the felicitous answers to the why-question change
depending on which constituent is focused. This can be explained if it is assumed that ‘why’lacks the focus feature, so that it can be associated with focus. On the other hand, the range ofthe answers to the ordinary wh-questions is not affected by focus-shift, as illustrated in (33).
(33)a. When did ADAM eat the apple?
---At 4PM on July 7, 24,000BC.
b. When did Adam EAT the apple?
--- At 4PM on July 7, 24,000BC.
c. When did Adam eat the APPLE?
--- At 4PM on July 7, 24,000BC.

Focus and Wh-features in Interrogative C (K. Takita)This fact can be explained if we assume that the ordinary wh-phrases are inherently focused,
so that it cannot be associated with focus. Thus, we conclude that wh-phrases in general havethe focus feature, while ‘why’ lacks it.
Then, let’s turn to the nature of SBEs. Based on Kim’s (2002) claim that the source of theintervention effect is the focus-relatedness of SBEs, we assume that SBEs have the focus
feature, which is checked by its counterpart on C (see also Aoyagi 1994 for the similar
proposal).
Now, we have briefly specified what lexical items have what features. They aresummarized in (34).
(34)Feature Specifications of Lexical Items (preliminary)a. SBEsb. wh-phrasesc. ‘why’d. interrogative C

Q-feature---√√√

Focus-feature√√---optional

Here, we got the answers to the questions in (29). Compare the feature specifications of thewh-phrases and ‘why’. The answer to (29a) is that wh-phrases and ‘why’ differ in the absenceof the focus feature. Next, compare SBEs, wh-phrases, and ‘why’. The answer to the questionin (29b) is the following; SBEs and ‘why’ are similar in that the feature which they haveconstitutes the proper subset of the features which the ordinary wh-phrases have.
So, let us reconsider the configurations under the feature specifications in (34). They aresummarized in (35).
(35)a.

ok[… C{Q, Foc} … wh{Q, Foc} … SBE{Foc}/ ‘why’{Q} …]

b. *[… C{Q, Foc} … SBE{Foc}/ ‘why’{Q} … wh{Q, Foc} …]
c.

ok[… C{Q, Foc} … SBE{Foc} … ‘why’{Q} …]d.

ok[… C{Q, Foc} … ‘why’{Q} … SBE{Foc} …]

At this point, we can revise the preliminary generalization in (28) to (36).
(36)Generalization on the Word Order (revised)
α can enter the checking relation with a head H iff there is no intervening β whichcontains the proper subset of the features relevant to the checking relation.
This generalization can correctly distinguish the ill-formed (35b) from the other well-formed
configurations. In Section 3.2.2, we will derive this generalization.

- 143 -

Nanzan Linguistics: Special Issue 1, Vol. 1

Before continuing, it is worth pointing out that a split-CP system, in which each C hosts
the Q-feature and the focus feature separately, is incompatible with the generalization (36).
Consider the configuration in (37a), where an SBE precedes a wh-phrase. Note that thisordering should be ruled out. The derivation proceeds as illustrated in (37b).
(37)a. [CP2 C2{Q} [CP1 C1{Foc} [IP … SBE{Foc} … wh{Q, Foc} …]]]
b. Step 1; The SBE enters checking relation with C111
[CP2 C2{Q} [CP1 C1{Foc} [IP … SBE{Foc} … wh{Q, Foc} …]]]
Step 2; The wh-phrase enters a checking relation with C2[CP2 C2{Q} [CP1 C1{Foc} [IP … SBE{Foc} … wh{Q, Foc} …]]]

Under the generalization (36), the Step 2 in (37b) counts as legitimate, because the feature
relevant to this checking relation is only the Q-feature, and the SBE does not have it.
Therefore, the derivation converges, yielding the SBE-wh order, contrary to fact. Thus, inwhat follows, we will adopt the single-CP system.
3.1.2 To Find a Solution to the “Undesirable Scrambling” Problem
Another important issue is to solve the undesirable scrambling problem, which casts
serious doubt on Ko’s (2005, 2006) analysis. In fact, this problem arises even under the
single-CP system. Look at the derivation in (38).
(38)a. Step 1; Merge of C
[CP C{Q, Foc} [IP … wh{Q, Foc} … SBE{Foc} …]]
b. Step 2; The wh-phrase enters a checking relation with C, observing (36)
[CP C{Q, Foc} [IP … wh{Q, Foc} … SBE{Foc} …]]

c. Step 3; The SBE is scrambled to the highest CP-adjoined position[CP SBE{Foc} [CP C{Q, Foc} [IP … wh{Q, Foc} … tSBE …]]

In (38a), the wh-phrase precedes the SBE. This configuration is well-formed on par with(35a) so that the checking relation between the wh-phrase and the C head can observe thegeneralization (36), as indicated in (38b). In principle, once the checking relation isestablished, the SBE can be scrambled to the CP-adjoined position as in (38c). The derivation
can converge, yielding the ungrammatical SBE-wh order. As shown in (38), undesirable

Focus and Wh-features in Interrogative C (K. Takita)

scrambling is problematic because it obscures underlying checking relations. It is necessary toforbid the undesirable scrambling, without recourse to ad hoc assumptions.
In this subsection, we have argued that there are two things that have to be solved to givea uniform explanation to the paradigm in (27); the generalization on word order (36) and theundesirable scrambling problem. As a first step to solve the problem, we have suggested thatspecification of features on lexical items and the way of feature checking play a crucial role
to solve the problems. In Section 3.2, we further pursue this line of approach and implement
it in more specific way.
3.2 Implementation
3.2.1 More Precise Feature Specifications of Lexical Items
First, we revise the feature specifications of lexical items in (27), adopting the proposal
by Pesetsky and Torrego (2004). Their basic idea is that valuation of a feature is independentof interpretability of it; whether a feature is interpretable or not is irrelevant to whether it hasvalue or not. Thus, there are four logically possible repertoires of features, listed in (39).
(39)Repertoire of Possible Features
notationa. interpretable, valued[iX X]

b. interpretable, unvalued[iX ]c. uninterpretable, valued[uX X]

d. uninterpretable, unvalued[uX ]Examples[iQ Q]
on yes/no question C[iQ ]on wh-question C[uQ Q]
on wh-phrases[uQ ]on embedded declarative C which supports
successive cyclic wh-movement

The first one, in (39a), is interpretable valued feature [iX X]. One instance of this feature is [iQQ], which appears on yes/no-question C. The second possibility is the interpretable unvalued
feature [iX ]. Wh-question C has one instance of this type, namely [iQ ], which attracts a whphrase and gets valued from it. The third type is the uninterpretable valued feature [uX X],
which for example appears on wh-phrases as [uQ Q]. The last type is the uninterpretable
unvalued feature [uX ]. A concrete example of this type is [uQ ], which appears on theembedded declarative C, which supports successive cyclic wh-movement.
One important aspect of Pesetsky and Torrego’s (2004) theory is that a feature which isunvalued can act as probe, even though the feature is interpretable. Consider how their theory
derives a wh-question in (40a). We omit the focus features here.

- 145 -

Nanzan Linguistics: Special Issue 1, Vol. 1(40)a. [CP2 Whati do you think [CP1 t’i John bought ti]]?
b. Step 1; [uQ ] on the embedded C1 probes its domain, and it finds what as a goal12 13[CP1 C1{[uQ Q]} [IP … what{[uQ Q]} …]]
Step 2; C1 attracts what to Spec, CP1[CP1 what{[uQ Q] }i C1{[uQ Q] } [IP … ti …]]
Step 3; [iQ ] on the matrix C2 probes its domain, and it finds what as a goal
[CP2 C2{[iQ Q]} [IP … [CP1 what{[uQ Q]}i C1 [IP … ti …]]]]
Step 4; C2 attracts what to Spec, CP2[CP2 what{[uQ Q]}i C2{[iQ Q]} [IP … [CP1 t’i C1 [IP … ti …]]]]

At the Step 1 in the derivation (40b), [uQ ] on the embedded C probes its domain and finds
the wh-phrase what as goal. Then, attracting the wh-phrase to its Spec, the embedded C getsvalued from it, so that [uQ ] is deleted. Given that an uninterpretable valued feature can bedeleted iff it is checked by interpretable features, [uQ Q] on the wh-phrase is not deleted. Then,the matrix C is introduced to the derivation as in the Step 2 in (40b), and [iQ ] on it probes its
domain and find what on the embedded Spec, CP as goal.14 It values [iQ ] on the matrix C
and by assumption, it can be deleted. In this way, Pesetsky and Torrego’s (2004) theory
makes it possible to derive successive cyclic wh-movement, postulating only one kind offeature, namely Q-feature.
Under Pesetsky and Torrego’s (2004) typology of features, we have to sharpen thefeature specification of the focus feature. Given that focus is a kind of clausal phenomena, it
is natural to assume that if a focus feature appears on C, it becomes interpretable, while if itappears on an SBE, which is a subpart of a clause, it becomes uninterpretable. Thus, we claimthat SBEs have [uF(oc) F], and C can optionally have [iF ].
Now, we have more precise feature specifications of lexical items, as listed in (41).

Here, we put aside the v*P phase for ease of exposition. It is possible to obtain the same result if we

Thus, the only way for them to be deleted is to be probed by interpretable unvalued
features, namely the features on C. On the other hand, under Chomsky’s (2000, 2001)
conception of interpretability and valuation, interpretable features always have value, so thatthey need not be checked. Therefore, since the focus feature on SBEs, for example, ispresumably valued, it must be interpretable. This difference between Pesetsky and Torrego(2004) and Chomsky (2000, 2001) becomes crucial when we solve the undesirable
scrambling problem. We will come back to this point later.
3.2.2 Analysis
Let us turn to the word order generalization in (39). To derive the generalization, we
propose the Valuation Condition (42).
(42)Valuation Condition
A probe P must utilize all valued features on a goal G for valuation of unvalued features
on P.
Let us examine how the Valuation Condition, combined with the feature specifications in (41)works. The schematic structure of the intervention/anti-superiority effect is shown in (43).
(43)a. *[… Q … SBE/‘why’ … wh …]b.

ok[… Q … wh … SBE/‘why’ …]

Below, we concentrate on the case of the intervention effect for ease of exposition. The antisuperiority effect can be explained essentially in the same way.
Given that the relevant features are not enter any checking relation within IP so thatscrambling freely change the order of wh-phrases and SBEs, we have two logically possible
configurations at the point where the matrix interrogative C is merged, as indicated in (44).
(44)a. Possibility 1; An SBE precedes a wh-phrase[CP C{[iQ ], [iF ]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} …]]- 147 -

Nanzan Linguistics: Special Issue 1, Vol. 1

b. Possibility 2; A wh-phrase precedes an SBE[CP C{[iQ ], [iF ]} [IP … wh{[uQ Q], [uF F]} … SBE{[uF F]} …]]First, let us consider the Possibility 1 in (44a). The derivation proceeds as in (45).
(45)Continuation of the Possibility 1
a. Step 1; C probes its domain, and it finds the SBE as a goal15[CP C{[iQ ], [iF F]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} …]]
b. Step 2; C probes its domain again, and it finds the wh-phrase as a goal16[CP C{[iQ ], [iF F]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} …]]X
As shown in (45a), C probes its domain, and finds the SBE as a goal, since the SBE
asymmetrically c-commands the wh-phrase at this step. Then, [iF ] on C is valued by [uF F]
on the SBE. Since C utilizes all features on the SBE, this step is legitimate. Then, C probes its
domain again as in (45b), and finds the wh-phrase as a goal. The probe, however, cannot
utilize [uF F] on the wh-phrase because [iF ] on C has been already valued at the Step 1.
Therefore, this step violates the Valuation Condition. As a result, the ungrammatical SBE-whorder is correctly ruled out.
Let us now turn to the Possibility 2 in (44b). Look at the derivation in (46).
(46)Continuation of the Possibility 2
a. Step 1; C probes its domain, and it finds the wh-phrase as a goal
[CP C{[iQ Q], [iF F]} [IP … wh{[uQ Q], [uF F]} … SBE{[uF F]} …]]

b. Step 2; The fully valued C check the uninterpretable feature on the SBE[CP C{[iQ Q], [iF F]} [IP … wh{[uQ Q], [uF F]} … SBE{[uF F]} …]]

C probes its domain and finds the wh-phrase as a goal, as illustrated in (46a). By the
Valuation Condition, C has to exhaust the features on the wh-phrase, namely [uQ Q] and [uF F],
so that all the unvalued features on C are valued. Then, the fully valued C can check [uF F] on
the SBE as in (46b). This step observes the Valuation Condition since no feature valuation
takes place. Therefore, the Possibility 2 converges, yielding the grammatical wh-SBE order.

15

In this subsection, we deal with the special case where all operations are covert. Next subsection
argues the interaction of overt and covert operations, although it does not affect the argument here.

A pair of features that is problematic for the relevant operation is indicated by screening.

Focus and Wh-features in Interrogative C (K. Takita)

Note that the explanation here crucially relies on the assumption that it is impossible tochange the IP-internal order of elements, which enter the checking relation with C. Therefore,
we have to ensure that the order of the relevant elements is preserved after feature checking.
To do so, we have to solve the undesirable scrambling problem. Here, we provide a solution
to the problem. Suppose that α contains an undeleted uninterpretable feature [uX X], and it isscrambled to the matrix CP-adjoined position, before C probes its domain. The structure in(47) is the relevant one.
(47)*[CP α{[uX X]} Cmatrix{[iX ]} [IP … tα …]]X

Given that scrambling does not involve any feature checking, and the search domain of aprobe is restricted to the sister of the head, there is no way to check the undeleted [uX X] on α.
Therefore, such scrambling, namely “scrambling before feature checking”, always induces
ungrammatical result. Recall that SBEs, wh-phrases, and ‘why’ have uninterpretable features
under Pesetsky and Torrego’s (2004) theory. Thus, scrambling of them before featurechecking makes the derivation crash.
The derivation in (48) is one concrete example. In (48a), the SBE, which had followed
the wh-phrase within IP, is scrambled to the CP-adjoined position before C probes its domain.
(48)a. Step 1; SBE is scrambled before C probes its domain[CP SBE{[uF F]} C{[iQ ], [iF ]} [IP … wh{[uQ Q], [uF F]} … tSBE …]]

b. Step 2; C probes its domain, and it finds wh-phrase as a goal
[CP SBE{[uF F]} C{[iQ Q], [iF F]} [IP … wh{[uQ Q], [uF F]} … tSBE …]]Then, C probes its domain and finds the wh-phrase as a goal. Therefore, the features on thewh-phrase and C are successfully valued and deleted, observing the Valuation Condition.
However, the scrambled SBE still has the uninterpretable feature [uF F], and there is no way
to check it. Hence, the derivation crashes and the ungrammatical SBE-wh order is ruled out.
That is, it is scrambling of the SBE that makes the derivation crash. Note that under
Chomsky’s (2000, 2001) idea of feature interpretability and valuation, this situation is
unexpected. As we have seen above, SBEs are arguably valued so that interpretable.
Therefore, there is no reason for the derivation in (48) to crash, contrary to fact. Thus, theundesirable scrambling problem does offer an empirical argument for Pesetsky and Torrego’s(2004) conception of valuation/interpretability of features.
How does the proposed analysis deal with the absence of the intervention effect, repeatedhere in (49)?
(49)a.

ok[… Q … SBE … ‘why’ …]- 149 -

Nanzan Linguistics: Special Issue 1, Vol. 1b.

ok[… Q … ‘why’ … SBE]

At the point where the matrix interrogative C is introduced to the derivation, we have twologically possible configurations (50a) and (50b), because the features on the SBE and ‘why’
are not checked within IP, so that scrambling freely alter the ordering.
(50)a. Possibility 1; An SBE precedes ‘why’[CP C{[iQ ], [iF ]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} …]]
b. Possibility 2; ‘Why’ precedes an SBE[CP C{[iQ ], [iF ]} [IP … ‘why’{[uQ Q]} … SBE{[uF F]} …]]
Let us continue the derivation of the Possibility 1. Look at (51).
(51)Continuation of the Possibility 1
a. Step 1; C probes its domain, and it finds the SBE as a goal
[CP C{[iQ ], [iF F]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} …]]

b. Step 2; C probes its domain again, and it finds ‘why’ as a goal
[CP C{[iQ Q], [iF F]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} …]]

In this case, each step in (51) obeys the Valuation Condition, since each step utilizes the allvalued features on the goal, namely [uF F] on the SBE and [uQ Q] on ‘why’, respectively. Thus,
the derivation can converge, yielding the grammatical SBE-‘why’ order. The Possibility 2 in(50b) gets the same way. Look at the derivation in (52).
(52)Continuation of the Possibility 2
a. Step 1; C probes its domain, and it finds ‘why’ as a goal
[CP C{[iQ Q], [iF ]} [IP … ‘why’{[uQ Q]} … SBE{[uF F]} …]]

b. Step 2; C probes its domain again, and it finds the SBE as a goal
[CP C{[iQ Q], [iF F]} [IP … ‘why’{[uQ Q]} … SBE{[uF F]} …]]

In this case, the value of [iQ ] is valued first, because ‘why’ is closer to C than the SBE. Eachstep can observe the Valuation Condition, so that the grammatical ‘why’-SBE order can bederived.
To sum up this section, we argued that the feature specifications in (41) and the Valuation
Condition (42) can derive the effects of the generalization (36). We also argued that Pesetsky
and Torrego’s (2004) idea makes it possible for SBEs, wh-phrases, and ‘why’ to haveuninterpretable features, which in turn enables us to solve the undesirable scrambling- 150 -

Focus and Wh-features in Interrogative C (K. Takita)

problem; scrambling before feature checking is impossible. The next subsection, however,shows that the proposed analysis does not fully solve the problem yet; it cannot exclude thepossibility of “scrambling after feature checking”. We claim that this residual problem can besolved by assuming the proposals by Nissenbaum (2000) and Richards (2001), and argue that
this in turn provide a support for their proposals.
3.3 Solving the Residual Problem
To understand the problem of scrambling after feature checking, consider the derivationin (53).
(53)a. Step 1; Merge of C to IP, where the wh-phrase precedes the SBE[CP C{[iQ ], [iF ]} [IP … wh{[uQ Q], [uF F]} … SBE{[uF F]} …]]
b. Step 2; C probes its domain, and it finds the wh-phrase as a goal
[CP C{[iQ Q], [iF F]} [IP … wh{[uQ Q], [uF F]} … SBE{[uF F]} …]]

c. Step3; The fully valued C checks the uninterpretable feature on the SBE[CP C{[iQ Q], [iF F]} [IP … wh{[uQ Q], [uF F]} … SBE{[uF F]} …]]

d. Step 4; Scrambling of the SBE to the CP-adjoined position[CP SBE{[uF F]} C{[iQ Q], [iF F]} [IP … wh{[uQ Q], [uF F]} … tSBE …]]

As we have seen in the previous subsection, each step in (53b) and in (53c) is possible. The
problematic step is the Step 4 in (53d). If this step is in fact possible, the ungrammatical SBEwh order cannot be ruled out, because all the features have already cease to be problematic
until that point. Recall that the undesirable scrambling problem is a problem of scrambling
before feature checking. What happens here is the scrambling of the SBE after its featurechecking. Let us call this the “revived undesirable problem”. In the rest of this section, we
argue that this problem can be solved once we assume the theory by Nissenbaum (2000), whoclaims that all overt operations must precede the covert ones within a certain domain.
The central idea of Nissenbaum (2000) is that the overt component and the covert
component succeed each other. To embody this idea, Nissenbaum (2000) first assumes (54)and (55) (Nissenbaum 2000, p. 17).
(54) Pronunciation of Chains
A syntactic chain is spelled out in exactly one position --- the highest one possible.

- 151 -

Nanzan Linguistics: Special Issue 1, Vol. 1(55) Spellout Applies to the Internal Domain on Each Cycle
The spellout property of a head H is satisfied by applying rules of phonology to the sisterof H.
Then, Nissenbaum (2000) distinguishes overt and covert operations in the following way(Nissenbaum 2000, p. 13).
(56)The Difference between Overt and Covert Movement is Due to Sequencing
Operations that precede spellout are overt, while those that follow it are covert.
Under this distinction, if movement applies first, and then the internal domain of H is spelled
out, the moved phrase α is pronounced at the landing site, by the assumption in (54). Thissituation is illustrated in (57).
(57)a. Step 1; Movement of α
[HP … α … H [ … α …]]
b. Step 2; Spellout of the internal domain17[HP … α … H [ … <α> …]]This is the case of overt movement. On the other hand, if the internal domain of H is spelled
out first, the position where α is pronounced is determined at this point. Thus, thesubsequence movement cannot be overt, as indicated in (58).
(58)a. Step 1; Spellout of the internal domain[HP H [ … α …]]
b. Step 2; Movement of α
[HP … <α> … H [ …

α …]]This yields covert movement. In this way, Nissenbaum’s (2000) theory ensures that within acertain domain, namely where the head H drives operations, all overt operations apply before
the covert ones do.
Now, we can dissolve the revived undesirable scrambling problem. Look at the derivationin (59).

17

A spelled out domain is indicated by [ …

Focus and Wh-features in Interrogative C (K. Takita)(59)a. Step 1; Both α and β undergo covert movement18[HP H{[iX X], [iY Y]} [H’P … α{[uX X]} … β{[uY Y]} …]]

b. Step 2; Scrambling of β
[HP β{[uY Y]} H{[iX X], [iY Y]} [H’P … α{[uX X]} … tβ …]]

Suppose that both α and β undergo covert movement and the unvalued features on H getvalued, as in (59a). This means that the internal domain of H, namely H’P has been alreadyspelled out at this point. Since by definition, scrambling is an overt operation, it is impossible
to apply it to the configuration in (59a). Therefore, the step in (59b), which is the “revived
undesirable” step, is impossible. This is the solution.
In addition to providing a solution to the revived undesirable scrambling problem,
Nissenbaum’s (2000) theory has another good point. So far, we have dealt with the cases inwhich all operations take place covertly. As we have seen above, what is crucial to our
explanation is to ensure that the ordering of elements which enter the checking relation with
C is not destroyed by feature checking itself. Interaction of overt and covert operations may
make it impossible to guarantee the word order preservation. Nissenbaum’s (2000)
mechanism coupled with Richards’ (2001) tucking-in, however, makes it possible to extend
the analysis to the cases where overt and covert operations interact.
Before continuing, let us clarify when spellout applies in Japanese. We claim thatspellout applies at any point during the head H is executing operations.19 In other words,
Japanese/Korean has both overt and covert movement options. Evidence for this claim comesfrom the radical reconstruction example (3b), repeated here as in (60).

18

Under Nissenbaum’s (2000) theory of movement, the more precise representation of (59a) shouldbe the following;(i) [HP <α{[uX X]}> <β{[uY Y]}> H{[iX X], [iY Y]} [ H’P …

α{[ uX X]}…

β{[ uY Y]}…]]

In the following discussion, however, we continue to use the conventional structure as if no movementtakes place in cases of covert movement, for expository purpose.

what-Acc-Nom-Nom

kat-ta]ka] siritagatteir-u]
buy-Past Q want-to-know-Pres‘Taroo wants to know what Hanako bought.’
In this example, the wh-phrase nani ‘what’ undergoes long-distance scrambling to the matrix
clause, taking its scope at the embedded CP. Given that long-distance scrambling must movethrough the edge of the embedded CP (see Saito 2003, 2005), nani ‘what’ has to stop at theedge, establishing a checking relation with the embedded C to take the embedded scope.
Under our current assumptions, however, it is impossible to establish the relation by
scrambling to the CP-adjoined position, because scrambling does not involve any featurechecking. Meanwhile, if only the covert option is available to check [uQ Q] on nani ‘what’, it
is impossible to move the wh-phrase to the edge of the embedded CP, because scrambling is
no longer available after the covert feature checking. Hence, there is no way to scramble thewh-phrase to the matrix CP. Therefore, it is necessary to assume the overt movement option,in addition to the covert one. If this is the case, it in turn implies spellout can apply at any
point during the relevant head is active.
Bearing this mind, let us see how the order of elements is preserved. Consider theconfiguration in (61), where the internal domain H’P contains two elements which must be
checked by H.
(61)[HP H{[iX ], [iY ]} [H’P … α{[uX X]} … β{[uY Y]} …]]Since there are two elements α and β, and two movement options, we have four logicallypossible combinations. The first possibility is that both of them undergo covert movement, asin (62). Of course, the order cannot be changed.
(62)Order Preservation Case 1; both α and β undergo covert movement[HP H{[iX X], [iY Y]} [H’P … α{[uX X]} … β{[uY Y]} …]]

The second one is the case where α moves overtly and β moves covertly, as in (63).
(63)Order Preservation Case 2; α moves overtly and β moves covertly[HP α{[uX X]} H{[iX X], [iY Y]} [H’P … tα … β{[uY Y]} …]]

Scrambling of β is no longer available, so that it cannot precede α within HP. The third
possibility is that α moves covertly while β moves overtly, which yields the structure in (64).

Focus and Wh-features in Interrogative C (K. Takita)(64)Order Preservation Case 3; α moves covertly while β moves overtly[HP β{[uY Y]} H{[iX X], [iY Y]} [H’P … α{[uX X]} … tβ …]]

In this case, the order between α and β is reversed after feature-checking. However, this caseis straightforwardly ruled out by Nissenbaum’s (2000) mechanism. Since α is closer to H thanβ, H find α as a goal first, and moves it covertly. This means that spellout of H’P has alreadybeen applied until this point. Thus, the subsequent movement of β cannot be overt. Therefore,
the structure in (64) is impossible. The last possibility is to move both α and β overtly. At thispoint, Richards’ (2001) tucking-in condition plays an important role. Assuming the tucking-in
condition, Nissenbaum (2000) claims that the closer element moves first, and the second
movement tucks the constituent in the lower Spec position. This case is illustrated in (65).
(65)Order Preservation Case 4; both α and β undergo overt movement[HP α{[uX X]} β{[uY Y]} H{[iX X], [iY Y]} [H’P … tα … tβ …]]

As a result of tucking-in, the closer element α still precedes β after the feature-checking.
Therefore, in all cases the ordering of elements within HP can be preserved. Given a natural
assumption that the HP which executes spellout is CP, there is no position to scramble higher
than it except for the case where it is embedded, there is no way to alter the ordering of
relevant phrases. Here, we have the answer to the question in (8a), repeated here as (66).
(66)

Why the surface order of wh-phrases and SBEs is crucial to the grammaticality of asentence, given the optionality and the radical reconstruction property of scrambling?

The answer is; surface order is crucial because whether feature checking can obey the
Valuation Condition relies on the IP-internal order, and the IP-internal order cannot bechanged by feature-checking itself. In addition, scrambling either before or after featurechecking is impossible. In this way, Nissenbaum (2000) and Richards (2001) provide thesolution to answer the question in (66). This in turn supports for their theory because theirarguments are constructed on independent facts.
Let us summarize this section. First, we illustrated that the feature specification (41) andthe Valuation Condition (42) can derive the effects of the generalization (36), answering thequestion in (8b) and (8c). The answer is that the features which SBEs and ‘why’ haveconstitute only the proper subset of those which the ordinary wh-phrases have. Second, we
showed that the undesirable scrambling problem can be partially solved by Pesetsky and
Torrego’s (2004) proposal. Finally, we provided the full answer to the question in (8a),solving the residue of the undesirable scrambling problem, by assuming Nissenbaum (2000)
and Richards (2001).

4. Extension to Some Complex Cases
In this section, we extend the proposed mechanism to some more complex cases. First,
we show that the case which forces Ko (2006) to adopt the split-CP system can be explained,
without recourse to the split-CP system. Second, an apparent counterexample of theintervention effect is discussed.
4.1 Ko’s Motivation for the Split-CP System
This subsection argues that Ko’s (2006) motivation for the split-CP system can be
explained by the proposed mechanism which employs the single-CP system. Look at theexample in (17a), repeated here as (67).
(67)?

* Taroo-sika nani-o-only what-Acc

naze
why

tabe-nakat-ta
eat-not-Pastno?
Q‘Why did only Taroo eat what?’
Recall that under the CHM with single-CP system, (67) has the following structure.
(68)[CP SBEi whj ‘why’ C [IP … ti … tj …]]

Since ‘why’ is base-generated into Spec, CP, the fact the SBE and the wh-phrase precedes‘why’ indicates that they are scrambled to the positions which are higher than Spec, CP. In
this structure, the SBE does not block the checking relation between the wh-phrase and the C
head, so that it is wrongly predicated that the relevant example is grammatical. Thus, Ko(2006) abandons the single-CP system.
Let us consider how the proposed analysis rules out the example in (67). The importantfeature of the analysis is that the ordering of the relevant constituents is preserved. In otherwords, the surface order reflects the IP-internal order. Hence, the example has the following
structure at the point where the C head is introduced to the derivation.
(69)[CP C{[iQ ], [iF ]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} … ‘why’{[uQ Q]} …]

The derivation proceeds as follows.
(70)Continuation of (69)
a. Step 1; C probes its domain, and it finds the SBE as a goal20[CP C{[iQ ], [iF F]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} … ‘why’{[uQ Q]} …]

20

In what follows, we concentrate on the cases where all elements undergo covert movement for easeof exposition.

Focus and Wh-features in Interrogative C (K. Takita)b. Step 2; C probes its domain again, and it finds the wh-phrase as a goal
[CP C{[iQ ], [iF F]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} … ‘why’{[uQ Q]} …]X
At the Step 2 in (70b), C cannot utilize [uF F] on the wh-phrase, since [iF ] on C has been
already valued at the Step 1 in (70a). Therefore, the derivation crashes, violating theValuation Condition. Thus, the example in (67) can be explained without recourse to thesplit-CP system.
4.2 An Apparent Counterexample of the Intervention Effect
In this subsection, we discuss an apparent counterexample of the intervention effect,
where long-distance scrambling of an SBE interacts with a matrix wh-phrase. Look at theexamples in (71), cited form Saito (2005).
(71)a. Soko-ni-sikai dare-ga [CP Taroo-ga ti
there-to-only who-Nom-Nom

ik-anakat-ta to] Ziroo-ni it-ta
go-not-Past C-to say-Past‘Who said to Ziroo that it was only there that Taroo went?’no?

b. Tookyoo-kara-sikai dare-ga [CP nimotu-ga ti todok-anakat-ta to] Ziroo-ni it-tano?
-from-only who-Nom luggage-Nom arrive-not-Past C-to say-Past Q‘Who said to Ziroo that it was only from Tokyo that luggage arrived?’(ibid.)In these examples, the SBE undergoes long-distance scrambling to the matrix CP, andprecedes the matrix wh-subject. This, they have the following schematic structure.
(72)[CP Q … SBE … wh [CP … tSBE …]]

Although this should be the case of intervention effect, the examples are not ungrammatical.
The proposed mechanism, however, can deal with them. Look at the derivation in (73).
(73)a. Step 1; Formation of the embedded CP[CP C{[iF ]} [IP … SBE{[uF F]} …]]
b. Step 2; Overt movement of the SBE to the embedded Spec, CP[CP SBE{[uF F]} C{[iF F]} [IP … tSBE …]]

c. Step 3; Formation of the matrix IP[IP … wh{[uQ Q], [uF F]} … [CP SBE{[uF F]} C{[iF F]} [ IP …

d. Step 4; Long-distance scrambling of the SBE[IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} … [CP t’SBE … [ IP …

t SBE …]]…]

e. Step 5; Merge of the matrix C[CP C{[iQ ], [iF ]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} … [ CP t’ SBE ]…]…]f.

Step 6; C probes its domain, and it finds the wh-phrase as a goal
[CP C{[iQ Q], [iF F]} [IP … SBE{[uF F]} … wh{[uQ Q], [uF F]} …[ CP t’ SBE ]…]…]At the Step 1 in (73a), the embedded C head is introduced to the derivation with the optionalfeature [iF ]. Then, at the Step 2 in (73b), the SBE moves overtly to Spec, CP. [uF F] on the
SBE values [iF ] on the embedded C, and [uF F] on the SBE is deleted. Note that thismovement is not scrambling but overt movement, so that the uninterpretable feature can bedeleted. At the Step 3 in (73c), the matrix IP is formed with the subject wh-phrase. At theStep 4 in (73d), the SBE, which is in the edge of the embedded CP, undergoes long-distancescrambling to the matrix IP-adjoined position.21 At the Step 5 in (73e), the matrix C is merged.
Then, in the Step 6, C probes its domain. What is crucial here is that [uF F] on the SBE has
been already deleted until this step, so that the probe can skip the SBE. The probe finds thewh-phrase as the closest goal and values its own unvalued features, observing the Valuation
Condition. Therefore, the derivation converges successfully, yielding the desirable word
order.22
To sum up this section, we discussed the two cases; one is that a single clause contains an
SBE, a wh-phrase and ‘why’,23 and the other is the interaction of a wh-phrase in a higher
21

We are still ignoring the v*P phase.

22This analysis is consistent with Saito’s (2003, 2005) analysis of long-distance scrambling in its
spirit. Saito (2003, 2005) claims that long-distance scrambling is in fact movement of only phonetic
features, which results from the deletion of other features in the previous steps. See Saito (2003, 2005)
for details.
23

Aono (2006) observes an interesting pattern of co-occurrence of the relevant items. Look at theexample in (i).
(i) *Dono-gaka-sika
which-artist-only

naze
why

sore-oit-Acckak-anakat-ta
paint-not-Pastno?
Q‘(Lit.) Why did only which artist paint it?’In this example, the wh-phrase dono-gaka ‘which artist’ is combined with the NPI -sika ‘only’.
Although it precedes ‘why’, the sentence is ungrammatical. Under our proposals, there seems to be no
way to exclude this example since C can be fully valued by the wh-phrase first and then it can check[uQ Q] on ‘why’. We tentatively suggest that combination of a wh-phrase and an SBE causes somechange to the feature specification of the amalgam, leaving the precise contents of such change open.

5. Concluding Remarks
5.1 Major Results
In this paper, we discussed the word order restrictions among SBEs, wh-phrases, and‘why’, which are rather unexpected in relatively free word order languages like Japanese.
Through the discussion of these restrictions, we got the following major results. First, wegave a generalization which unifies the anti-superiority effect, and the intervention effect, andthe exception of the intervention effect, and proposed an analysis which can capture thegeneralization. At the same time, arguing that it is necessary to solve the undesirable
scrambling problem, and any theory which does not pay attention to this problem isinadequate, we developed the way to solve the problem. Second, we pointed out the analysis
which employs the split-CP system has several problems, while the problems can be solved
under the single-CP system. Finally, since the proposed mechanism crucially assumes that‘why’ is base-generated within IP, the CMH cannot be tenable at least for Japanese.
Let us go back to the questions in (8), which we made in Section 1, repeated here as (74).
(74)a. Why the surface order of wh-phrases and SBEs is crucial to the grammaticality of asentence, given the optionality and the radical reconstruction property of scrambling?
b. Why does naze ‘why’ behave differently from the other wh-phrases?
c. Why do SBEs induce the intervention effect?
We have the following answers; the answer to (74a): Surface order is crucial because underPesetsky and Torrego’s (2004) idea of feature interpretability and valuation, whether featurechecking can obey the Valuation Condition relies on the IP-internal order. In addition, the IPinternal order cannot be changed by feature checking itself, given the proposals by
Nissenbaum (2000) and Richards (2001). Further, scrambling either before or after featurechecking is also impossible, given the proposed mechanism. Therefore, the IP-internal orderis carried over to the surface order. The answer to (74b) is that naze ‘why’ differs from theother wh-phrases in that it lacks the focus feature. The answer to (74c): SBEs induce theintervention effect because their specifications of features which are checked by C are theproper subset of those of the ordinary wh-phrases, so that they always violate the Valuation
Condition when they precede the ordinary wh-phrases.
5.2 A Speculation on the Status of the CMH and the Split-CP System
Finally, we make a brief speculation. Recall that under the Ko’s (2005, 2006) original
formulation, the CMH is a hypothesis for wh-in-situ languages including Japanese, Korean,- 159 -

Nanzan Linguistics: Special Issue 1, Vol. 1

and Chinese. Yet, there are proposals which are akin to the CMH for not wh-in-situ
languages; see Rizzi (1999) for Italian and Hornstein (1995) for English. The suggesting fact
is that Chinese lacks the anti-superiority effect, as the contrast in (75) indicates.
(75)a. Zhangsan

(ibid.)

This fact can be explained if we assume that the CMH is true for Chinese and it lacks A’scrambling, as Ko (2006) claims. Thus, we speculate that the CMH may be true for VO
languages including Chinese, Italian, and English, not for wh-in-situ languages. In addition,
recall that the split-CP system can generate the ‘why’-wh order vacuously observing theValuation Condition, as we have seen in (37). The relevant derivation is repeated in (76).
(76)a. Step 1; Suppose that C1 and C2 hosts the Q-feature and the focus feature separately24[CP2 C2{[iF ]} [CP1 C1{[iQ ]} [IP … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]]
b. Step 2; C1 probes its domain, and it finds ‘why’ as a goal
[CP2 C2{[iF ]} [CP1 C1{[iQ Q]} [IP … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]]

c. Step 3; The fully valued C1 can check [uQ Q] on the wh-phrase[CP2 C2{[iF ]} [CP1 C1{[iQ Q]} [IP … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]]

d. Step 4; C2 probes its domain, and it finds the wh-phase as a goal
[CP2 C2{[iF F]} [CP1 C1{[iQ Q]} [IP … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]]

What is crucial here is the Step 3 in (76c). Since C1 hosts only [iQ ], it can freely check theuninterpretable features without violating the Valuation Condition, once it is valued. Thus,
the derivation converges, yielding the desirable word order. Thus, we speculate that inaddition to English and Italian, Chinese also employs the split-CP system.25 We further

24

The hierarchical order of two C heads is not relevant.

25

Everything else being equal, the proposed analysis predicts that if there is no anti-superiority effectin a language, the intervention effect is also absent. One problem of this approach is that Chinese infact shows the intervention effect. I thank to Barry C.-Y. Yang for pointing out this fact. We hope toreturn this issue in future works.

Focus and Wh-features in Interrogative C (K. Takita)

speculate that the CMH and the split-CP system are related to the head-parameter; head-initial
languages make use of the CMH and the split-CP system, while head-final ones are not.
Appendix: Some “Additional” Phenomena
1. Additional Wh-effect
In some circumstances, anti-superiority is evaded, as the contrast in (77) indicates.
(77)a. * Taroo-ga naze
-Nom why

nani-owhat-Acc

tabe-taeat-pastno?
Qtabe-taeat-Pastno?
Q‘Why did Taroo eat what?’b. Dare-ga
naze

nani-owhat-Acc‘(Lit.) Why did who eat what?’
If the subject is replaced to a wh-phrase as in (77b), the sentence becomes grammatical. Thisphenomenon is called the “additional wh-effect” (see A. Watanabe 1991, S. Watanabe 1994,
Saito 1994, and references cited therein), because the additional wh-phrase remedies the antisuperiority effect. They have the following schematic structures.
(78)* [… ‘why’ … wh …] ok[… wh1 … ‘why’ …wh2 …]

The proposed mechanism straightforwardly explains this observation. Look at the derivationin (79).
(79)a. Step 1; Merge of C
[CP C{[iQ ],[iF ]} [IP …wh1{[uQ Q],[uF F]}…‘why’{[uF F]}… wh2{[uQ Q],[uF F]}…]]
b. Step 2; C probes its domain, and it finds wh1 as a goal
[CP C{[iQ Q],[iF F]} [IP …wh1{[uQ Q],[uF F]}…‘why’{[uF F]}… wh2{[uQ Q],[uF F]}…]]

c. Step 3; The fully valued C can check the uninterpretable features on ‘why’ and wh2[CP C{[iQ Q],[iF F]} [IP …wh1{[uQ Q],[uF F]}…‘why’{[uF F]}… wh2{[uQ Q],[uF F]}…]]

Recall that the surface order reflects the IP-internal order. Hence, the example in (77b) has
the structure in the Step 1 in (79a) when the C head is merged. Then, C probes its domain andfinds wh1 as a goal. At this point, all the unvalued features on C can be valued. Therefore, the- 161 -

Nanzan Linguistics: Special Issue 1, Vol. 1

subsequent feature checking can observe the Valuation Condition, so that the derivation canconverge. In this way, the additional wh-effect can be explained.
2. New Observation; “Additional SBE Effect”
Here, we discuss a prediction of the proposed analysis and show that the prediction isborne out, providing a new observation. First, suppose that we have the configuration shownin (80a).
(80)a. Step 1; Merge of C
[CP C{[iQ ], [iF ]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]
b. Step 2; C probes its domain, and it finds the SBE as a goal
[CP C{[iQ ], [iF F]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]

c. Step 3; C probes its domain, and it finds ‘why’ as a goal
[CP C{[iQ Q], [iF F]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]

d. Step 4; The fully valued C can check the uninterpretable features on the wh-phrase[CP C{[iQ Q], [iF F]} [IP … SBE{[uF F]} … ‘why’{[uQ Q]} … wh{[uQ Q], [uF F]} …]]

At the next step in (80b), C can utilize all the valued features on the SBE, obeying theValuation Condition. The subsequence step in (80c) also observes it, since ‘why’ lacks [uF F].
Then, C is fully valued, so that its can check the uninterpretable features on the wh-phrase,
violating nothing. Hence, the derivation converges. Therefore, the mechanism allows thistype of ordering, that is SBE-‘why’-wh or ‘why’-SBE-wh. This prediction is borne out. Lookat the examples in (81) and (82).

In these examples, (81b) and (82b) are the cases of the exception of the intervention effect.
There is no significant difference in grammaticality between (81a) and (81b), and (82a) and(82b), respectively.
In particular, the case of (81) is interesting. Note that in (81a), if the subject is not an SBE,
the sentence should be ruled out as an instance of anti-superiority. That is, the anti-superiority
effect can be remedied by an additional SBE, as illustrated in (83a).
(83)a. *[… ‘why’ … wh …]

okb. *[… ‘why’ … wh …]ok[… SBE … ‘why’ … wh …][… wh1 … ‘why’ … wh2 …]

The situation is reminiscent of the additional wh-effect (78), repeated here as (83b). Thus, wecall this phenomenon the “additional SBE effect”.
