# V2 word order

In syntax, verb-second (V2) word order is a sentence structure in which the finite verb of a sentence or a clause is placed in the clause's second position, so that the verb is preceded by a single word or group of words (a single constituent).
Examples of V2 in English include (brackets indicating a single constituent):
If English used V2 in all situations, then it would feature such sentences as:
V2 word order is common in the Germanic languages and is also found in Northeast Caucasian Ingush, Uto-Aztecan O'odham, and fragmentarily in Romance Sursilvan (a Rhaeto-Romansh variety) and Finno-Ugric Estonian. Of the Germanic family, English is exceptional in having predominantly SVO order instead of V2, although there are vestiges of the V2 phenomenon.
Most Germanic languages do not normally use V2 order in embedded clauses, with a few exceptions. In particular, German, Dutch, and Afrikaans revert to VF (verb final) word order after a complementizer; Yiddish and Icelandic do, however, allow V2 in all declarative clauses: main, embedded, and subordinate. Kashmiri (an Indo-Aryan language) has V2 in 'declarative content clauses' but VF order in relative clauses.

## Examples

The example sentences in (1) from German illustrate the V2 principle, which allows any constituent to occupy the first position as long as the second position is occupied by the finite verb. Sentences (1a) through to (1d) have the finite verb spielten 'played' in second position, with various constituents occupying the first position: in (1a) the subject is in first position; in (1b) the object is; in (1c) the temporal modifier is in first position; and in (1d) the locative modifier is in first position.

In this example, English is more straightforward to compare to a North Germanic language: The same inversions occur regularly in the North Germanic languages, and in Dutch, for that matter, but English uses the North Germanic word order apart from having lost the inversions in common use.

The caveat here (unlike in German) is that in languages without grammatical case, the form with the object first (2b) can only be used unambiguously when the object is unmistakable from the subject, such as if it is a personal pronoun, or as in this example, cannot meaningfully be the subject. In speech, such inversions are usually marked with emphasis: Apart from inversions that are obligatory in their grammatical context, such as "jeg tenker, derfor er jeg" (I think, therefore am I), when an inversion occurs for no other reason than emphasis, which is what opens up for possible ambiguity, the word in the emphasized position before the verb is usually also emphasized in speech.

## Classical accounts

In major theoretical research on V2 properties, researchers discussed that verb-final orders found in German and Dutch embedded clauses suggest an underlying SOV order with specific syntactic movement rules which change the underlying SOV order, deriving a surface form where the finite verb is in the second position of the clause.
We first see a "verb preposing" rule, which moves the finite verb to the left-most position in the sentence, then a "constituent preposing" rule, which moves a constituent in front of the finite verb. Following these two rules will always result with the finite verb in second position. "I like the man":
Ich
I

## Non-finite verbs and embedded clauses
### Non-finite verbs

The V2 principle regulates the position of finite verbs only; its influence on non-finite verbs (infinitives, participles, etc.) is indirect. Non-finite verbs in V2 languages appear in varying positions depending on the language. In German and Dutch, for instance, non-finite verbs appear after the object (if one is present) in clause final position in main clauses (OV order). Swedish and Icelandic, in contrast, position non-finite verbs after the finite verb but before the object (if one is present) (VO order). That is, V2 operates on only the finite verb.

### Embedded clauses

(In the following examples, finite verb forms are in bold, non-finite verb forms are in italics and subjects are underlined.)
Germanic languages vary in the application of V2 order in embedded clauses. They fall into three groups.

#### Swedish, Danish, Norwegian, Faroese

In these languages, the word order of clauses is generally fixed in two patterns of conventionally numbered positions. Both end with positions for (5) non-finite verb forms, (6) objects, and (7), adverbials.
In main clauses, the V2 constraint holds. The finite verb must be in position (2) and sentence adverbs in position (4). The latter include words with meanings such as 'not' and 'always'. The subject may be position (1), but when a topical expression occupies the position, the subject is in position (3).
In embedded clauses, the V2 constraint is absent. After the conjunction, the subject must immediately follow; it cannot be replaced by a topical expression. Thus, the first four positions are in the fixed order (1) conjunction, (2) subject, (3) sentence adverb, (4) finite verb
The position of the sentence adverbs is important to those theorists who see them as marking the start of a large constituent within the clause. Thus the finite verb is seen as inside that constituent in embedded clauses, but outside that constituent in V2 main clauses.

'because this time he had unfortunately not wanted to send the documents before the meeting.'
Faroese Unlike continental Scandinavian languages, the sentence adverb may either precede or follow the finite verb in embedded clauses. A (3a) slot is inserted here for the following sentence adverb alternative.

'although people have never caught fish here'

#### German

In main clauses, the V2 constraint holds. As with other Germanic languages, the finite verb must be in the second position. However, any non-finite forms must be in final position. The subject may be in the first position, but when a topical expression occupies the position, the subject follows the finite verb.
In embedded clauses, the V2 constraint does not hold. The finite verb form must be adjacent to any non-finite at the end of the clause.
German grammarians traditionally divide sentences into fields. Subordinate clauses preceding the main clause are said to be in the first field (Vorfeld), clauses following the main clause in the final field (Nachfeld).
The central field (Mittelfeld) contains most or all of a clause, and is bounded by left bracket (Linke Satzklammer) and right bracket (Rechte Satzklammer) positions.
In main clauses, the initial element (subject or topical expression) is said to be located in the first field, the V2 finite verb form in the left bracket, and any non-finite verb forms in the right bracket. In embedded clauses, the conjunction is said to be located in the left bracket, and the verb forms in the right bracket. In German embedded clauses, a finite verb form follows any non-finite forms.
German

'He didn't ring you yesterday because he didn't want to disturb you.' b.Sobald er Zeit hatwirderdichanrufen As soon as he has timewillheyouring ...'When he has time he will ring you.' Embedded clausec.dasserdichgesternnichtangerufen hat thatheyouyesterdaynotrung has ...'that he didn't ring you yesterday'

#### Dutch and Afrikaans

V2 word order is used in main clauses; the finite verb must be in the second position. However, in subordinate clauses two word orders are possible for the verb clusters.
Main clauses:
Dutch
    First fieldLeft bracketCentral fieldRight bracketFinal field Main clausea.De MāorihebbenNieuw-Zeelandontdekt The MāorihaveNew Zealanddiscovered ...'The Māori have discovered New Zealand.' b.Tussen ongeveer 1250 en 1300ontdektende MāoriNieuw-Zeeland Between approximately 1250 and 1300discoveredthe MāoriNew Zealand ...'Between about 1250 and 1300, the Māori discovered New Zealand.' c.Niemandhadgedachtdat ook maar iets zou gebeuren. Nobodyhadthought ...'Nobody figured that anything would happen.' Embedded claused.datde MāoriNieuw-Zeelandhebben ontdekt thatthe MāoriNew Zealandhave discovered ...'that the Māori have discovered New Zealand'
This analysis suggests a close parallel between the V2 finite form in main clauses and the conjunctions in embedded clauses. Each is seen as an introduction to its clause-type, a function which some modern scholars have equated with the notion of specifier. The analysis is supported in spoken Dutch by the placement of clitic pronoun subjects. Forms such as ze cannot stand alone, unlike the full-form equivalent zij. The words to which they may be attached are those same introduction words: the V2 form in a main clause, or the conjunction in an embedded clause.
    First fieldLeft bracketCentral fieldRight bracketFinal field Main clausee.Tussen ongeveer 1250 en 1300ontdekten-zeNieuw-Zeeland between approximately 1250 and 1300discovered-theyNew Zealand ...'Between about 1250 and 1300, they discovered New Zealand.' Embedded clausef.dat-zetussen ongeveer 1250 en 1300Nieuw-Zeelandhebben ontdekt that-theybetween approximately 1250 and 1300New Zealandhave discovered ...'that they have discovered New Zealand between about 1250 and 1300'
Subordinate clauses:
In Dutch subordinate clauses two word orders are possible for the verb clusters and are referred to as the "red": omdat ik heb gewerkt, "because I have worked": like in English, where the auxiliary verb precedes the past particle, and the "green": omdat ik gewerkt heb, where the past particle precedes the auxiliary verb, "because I worked have": like in German. In Dutch, the green word order is the most used in speech, and the red is the most used in writing, particularly in journalistic texts, but the green is also used in writing as is the red in speech. Unlike in English however adjectives and adverbs must precede the verb: ''dat het boek groen is'', "that the book green is".

#### V2 in Icelandic and Yiddish

These languages freely allow V2 order in embedded clauses.
Icelandic Two word-order patterns are largely similar to continental Scandinavian. However, in main clauses an extra slot is needed for when the front position is occupied by Það. In these clauses the subject follows any sentence adverbs. In embedded clauses, sentence adverbs follow the finite verb (an optional order in Faroese).
    main clause embedded clauseFront —Finite verb ConjunctionSubject Subject— Finite verbSentence adverb Sentence adverbSubject —Non-finite verb Non-finite verbObject ObjectAdverbial Adverbial main clausea.Margirhöfðualdreilokiðverkefninu.

In more radical contrast with other Germanic languages, a third pattern exists for embedded clauses with the conjunction followed by the V2 order: front-finite verb-subject.
    ConjunctionFront (Topic adverbial)Finite verbSubject e.Jónefastum aðá morgunfariMaríasnemmaá fætur. JohndoubtsthattomorrowgetMaryearlyup...'John doubts that Mary will get up early tomorrow.' ConjunctionFront (Object)Finite verbSubject f.Jónharmaraðþessa bókskuliéghafalesið. Johnregretsthatthis bookshallIhaveread...'John regrets that I have read this book.'
Yiddish Unlike Standard German, Yiddish normally has verb forms before Objects (SVO order), and in embedded clauses has conjunction followed by V2 order.
    Front (Subject)Finite verbConjunctionFront (Subject)Finite verb a.ikhhobgezenmitvokh,azikhvelnitkenenkumendonershtik IhaveseenWednesdaythatIwillnotcancomeThursday...'I saw on Wednesday that I wouldn't be able to come on Thursday.'

### Root clauses

One type of embedded clause with V2 following the conjunction is found throughout the Germanic languages, although it is more common in some than it is others. These are termed root clauses. They are declarative content clauses, the direct objects of so-called bridge verbs, which are understood to quote a statement. For that reason, they exhibit the V2 word order of the equivalent direct quotation.
Danish Items other than the subject are allowed to appear in front position.
    ConjunctionFront (Subject)Finite verb a.VivedatBoikkeharlæstdenne bog WeknowthatBonothasreadthis book...'We know that Bo has not read this book.' ConjunctionFront (Object)Finite verbSubject b.Vivedatdenne bogharBoikkelæst Weknowthatthis bookhasBonotread...'We know that Bo has not read this book.'
Swedish Items other than the subject are occasionally allowed to appear in front position. Generally, the statement must be one with which the speaker agrees.
    ConjunctionFront (Adverbial)Finite verbSubject d.Jagtroratti det fallethardurätt Ithinkthatin that respecthaveyouright...'I think that in that respect you are right.'
This order is not possible with a statement with which the speaker does not agree.
    ConjunctionFront (Adverbial)Finite verbSubject e.*Jagtrorinteatti det fallethardurätt(The asterisk signals that the sentence is not grammatically acceptable.) Ithinknotthatin that respecthaveyouright...'I don't think that in that respect you are right.'
Norwegian
    ConjunctionFront (Adverbial)Finite verbSubject f.hunfortalteattil fødselsdagenhaddehunfåttkunstbok(Bokmål variety) shetoldthatfor her birthdayhad'shereceivedart-book...'She said that for her birthday she had been given a book on art.'
German Root clause V2 order is possible only when the conjunction dass is omitted. In such cases, formal usage also places the finite verb form into the present subjunctive (German Konjunktiv I) if the verb form is clearly distinguishable from the indicative; if not, the past subjunctive (German Konjunktiv II) is used.
    ConjunctionFront (Subject)Finite verb g.*Erbehauptet,dasserhateszur Postgebracht(The asterisk signals that the sentence is not grammatically acceptable.) h.Erbehauptet,erhabeeszur Postgebracht heclaims(that)hehasitto the post officetaken...'He claims that he took it to the post office.' By contrast, a form with an embedded first-person subject would usually use the past subjunctive here, since the present indicative and subjunctive appear identical: Er behauptet, ich hätte (instead of habe) es zur Post gebracht.
Compare the normal embed-clause order after dass

### Perspective effects on embedded V2

There are a limited number of V2 languages that can allow for embedded verb movement for a specific pragmatic effect similar to that of English. This is due to the perspective of the speaker. Languages such as German and Swedish have embedded verb second. The embedded verb second in these kinds of languages usually occur after 'bridge verbs'.
(Bridge verbs are common verbs of speech and thoughts such as "say", "think", and "know", and the word "that" is not needed after these verbs. For example: I think he is coming.)
Jag
I
ska
will
säga
say
dig
you
att
that
jag
I

inte

a

dew

interested.
(Swedish)
Jag ska säga dig att jag är inte ett dugg intresserad.
I will say you that I am not a dew interested.
"I tell you that I am not the least bit interested." → In this sentence, "tell" is the bridge verb and "am" is an embedded verb second.
Based on an assertion theory, the perspective of a speaker is reaffirmed in embedded V2 clauses. A speaker's sense of commitment to or responsibility for V2 in embedded clauses is greater than a non-V2 in embedded clause. This is the result of V2 characteristics. As shown in the examples below, there is a greater commitment to the truth in the embedded clause when V2 is in place.

→ In a V2 embedded clause, the speaker is committed to the truth of the statement "Maria thinks ..." and also the proposition "Peter is happy".

## Variations

Variations of V2 order such as V1 (verb-initial word order), V3 and V4 orders are widely attested in many Early Germanic and Medieval Romance languages. These variations are possible in the languages however it is severely restricted to specific contexts.

### V1 word order

V1 (verb-initial word order) is a type of structure that contains the finite verb as the initial clause element. In other words the verb appears before the subject and the object of the sentence.

### V3 word order

V3 (verb-third word order) is a variation of V2 in which the finite verb is in third position with two constituents preceding it. In V3, like in V2 word order, the constituents preceding the finite verb are not categorically restricted, as the constituents can be a DP, a PP, a CP and so on.

## Left edge filling trigger (LEFT)

V2 is fundamentally derived from a morphological obligatory exponence effect at sentence level. The left edge filling trigger (LEFT) effects are usually seen in classical V2 languages such as Germanic languages and Old Romance languages. The left edge filling trigger is independently active in morphology as EPP effects are found in word-internal levels. The obligatory exponence derives from absolute displacement, ergative displacement and ergative doubling in inflectional morphology. In addition, second position rules in clitic second languages demonstrate post-syntactic rules of LEFT movement. Using the language Breton as an example, absence of a pre-tense expletive will allow for the LEFT to occur to avoid tense-first. The LEFT movement is free from syntactic rules which is evidence for a post-syntactic phenomenon. With the LEFT movement, V2 word order can be obtained as seen in the example below.
Bez
EXPL
'nevo
Fin.[will.have]
hennex
he
traou
things
(in Breton)
Bez 'nevo hennex traou
EXPL Fin.[will.have] he things
"He will have goods"
In this Breton example, the finite head is phonetically realized and agrees with the category of the preceding element. The pre-tense "Bez" is used in front of the finite verb to obtain the V2 word order. (finite verb "nevo" is bolded).

## Syntactic verb second

It is said that V2 patterns are a syntactic phenomenon and therefore have certain environments where it can and cannot be tolerated. Syntactically, V2 requires a left-peripheral head (usually C) with an occupied specifier and paired with raising the highest verb-auxiliary to that head. V2 is usually analyzed as the co-occurrence of these requirements, which can also be referred to as "triggers". The left-peripheral head, which is a requirement that causes the effect of V2, sets further requirements on a phrase XP that occupies the initial position, so that this phrase XP may always have specific featural characteristics.

## English

Modern English differs greatly in word order from other modern Germanic languages, but earlier English shared many similarities. For this reason, some scholars propose a description of Old English with V2 constraint as the norm. The history of English syntax is thus seen as a process of losing the constraint.

#### Position of object

In examples b, c and d, the object of the clause precedes a non-finite verb form. Superficially, the structure is verb-subject-object- verb. To capture generalities, scholars of syntax and linguistic typology treat them as basically subject-object-verb (SOV) structure, modified by the V2 constraint. Thus Old English is classified, to some extent, as an SOV language. However, example a represents a number of Old English clauses with object following a non-finite verb form, with the superficial structure verb-subject-verb object. A more substantial number of clauses contain a single finite verb form followed by an object, superficially verb-subject-object. Again, a generalisation is captured by describing these as subject–verb–object (SVO) modified by V2. Thus Old English can be described as intermediate between SOV languages (like German and Dutch) and SVO languages (like Swedish and Icelandic).

#### Effect of subject pronouns

When the subject of a clause was a personal pronoun, V2 did not always operate.
forðon
therefore
we
we
sceolan
must
mid
with
ealle
all
mod
mind
and
mægene

God
gecyrran
turn
forðon we sceolan mid ealle mod & mægene to Gode gecyrran
therefore we must with all mind and power to God turn
'Therefore, we must turn to God with all our mind and power
However, V2 verb-subject inversion occurred without exception after a question word or the negative ne, and with few exceptions after þa even with pronominal subjects.

þa foron hie mid þrim scipum ut
then sailed they with three ships out
'Then they sailed out with three ships.'
Inversion of a subject pronoun also occurred regularly after a direct quotation.
"Me

said
hēo

Þīn

thankfulness
"Me is," cwæð hēo Þīn cyme on miclum ðonce"
{to me} is said she your coming in much thankfulness
'"Your coming," she said, "is very gratifying to me".'

#### Embedded clauses

Embedded clauses with pronoun subjects were not subject to V2. Even with noun subjects, V2 inversion did not occur.
...þa ða
...when
his
his
leorningcnichtas

...when his disciples him asked for whose sins the man became thus blind
'...when his disciples asked him for whose sins the man was thus born blind'

#### Yes–no questions

In a similar clause pattern, the finite verb form of a yes–no question occupied the first position
Truwast
trust
ðu
you
nu
now
þe

selfum
self

Truwast ðu nu þe selfum and þinum geferum bet þonne ðam apostolum...?
trust you now you self and your companions better than the apostles
'Do you now trust yourself and your companions better than the apostles...?'

### Middle English
#### Continuity

Early Middle English generally preserved V2 structure in clauses with nominal subjects.
On
in
þis
this

in this year wanted the king Stephen seize Robert
'During this year King Stephen wanted to seize Robert.'
Nu

look
euerich
every
man
man

to
himseleun
himself
Nu loke euerich man toward himseleun
now look every man to himself
'Now it's for every man to look to himself.'
As in Old English, V2 inversion did not apply to clauses with pronoun subjects.
bi
by
þis
this

#### Change

Late Middle English texts of the fourteenth and fifteenth centuries show increasing incidence of clauses without the inversion associated with V2.
sothely
Truly
se
the
ryghtwyse
righteous
sekys

Negative clauses were no longer formed with ne (or na) as the first element. Inversion in negative clauses was attributable to other causes.

### Vestiges in Modern English

As in earlier periods, Modern English normally has subject-verb order in declarative clauses and inverted verb-subject order in interrogative clauses. However these norms are observed irrespective of the number of clause elements preceding the verb.

#### Classes of verbs in Modern English: auxiliary and lexical

Inversion in Old English sentences with a combination of two verbs could be described in terms of their finite and non-finite forms. The word which participated in inversion was the finite verb; the verb which retained its position relative to the object was the non-finite verb. In most types of Modern English clause, there are two verb forms, but the verbs are considered to belong to different syntactic classes. The verbs which participated in inversion have evolved to form a class of auxiliary verbs which may mark tense, aspect and mood; the remaining majority of verbs with full semantic value are said to constitute the class of lexical verbs. The exceptional type of clause is that of declarative clause with a lexical verb in a present simple or past simple form.

#### Questions

Like Yes/No questions, interrogative Wh- questions are regularly formed with inversion of subject and auxiliary. Present Simple and Past Simple questions are formed with the auxiliary do, a process known as do-support.
    a. Which game is Sam watching? b. Where does she live?
          (see subject-auxiliary inversion in questions)

#### With topic adverbs and adverbial phrases

In certain patterns similar to Old and Middle English, inversion is possible. However, this is a matter of stylistic choice, unlike the constraint on interrogative clauses.
negative or restrictive adverbial first
    c. At no point will he drink Schnapps. d. No sooner had she arrived than she started to make demands.
          (see negative inversion)
comparative adverb or adjective first
    e. So keenly did the children miss their parents, they cried themselves to sleep. f. Such was their sadness, they could never enjoy going out.
After the preceding classes of adverbial, only auxiliary verbs, not lexical verbs, participate in inversion
locative or temporal adverb first
    g. Here comes the bus. h. Now is the hour when we must say goodbye.
prepositional phrase first
    i. Behind the goal sat many photographers. j. Down the road came the person we were waiting for.
          (see locative inversion, directive inversion)
After the two latter types of adverbial, only one-word lexical verb forms (Present Simple or Past Simple), not auxiliary verbs, participate in inversion, and only with noun-phrase subjects, not pronominal subjects.

#### Direct quotations

When the object of a verb is a verbatim quotation, it may precede the verb, with a result similar to Old English V2. Such clauses are found in storytelling and in news reports.
    k. "Wolf! Wolf!" cried the boy. l. "The unrest is spreading throughout the country," writes our Jakarta correspondent.
          (see quotative inversion)

#### Declarative clauses without inversion

Corresponding to the above examples, the following clauses show the normal Modern English subject-verb order.
Declarative equivalents
    a′. Sam is watching the Cup games. b′. She lives in the country.
Equivalents without topic fronting
    c′. He will at no point drink Schnapps. d′. She had no sooner arrived than she started to make demands. e′. The children missed their parents so keenly that they cried themselves to sleep. g′. The bus is coming here. h′. The hour when we must say goodbye is now. i′. Many photographers sat behind the goal. j′. The person we were waiting for came down the road. k′. The boy cried "Wolf! Wolf!" l′. Our Jakarta correspondent writes, "The unrest is spreading throughout the country" .

## French

Modern French is a subject-verb-object (SVO) language like other Romance languages (though Latin was a subject-object-verb language). However, V2 constructions existed in Old French and were more common than in other early Romance language texts. It has been suggested that this may be due to influence from the Germanic Frankish language. Modern French has vestiges of the V2 system similar to those found in modern English.
The following sentences have been identified as possible examples of V2 syntax in Old French:
    a.Old FrenchLongetempsfulyroysElinasenlamontaigne Modern FrenchLongtempsfutleroiElinasdanslamontagne....'Pendant longtemps le roi Elinas a été dans les montagnes.' EnglishFor a long timewasthekingElinasinthemountain...'King Elinas was in the mountains for a long time.'
    b.Old FrenchIteusesparolesdistrentlifreredeLancelot Modern FrenchTellesparolesdirentlesfrèresdeLancelot....'Les frères de Lancelot ont dit ces paroles' EnglishSuchwordsutteredthebrothersofLancelot....'Lancelot's brothers spoke these words.'
    c.Old FrenchAtantregardacontrevallamer Modern FrenchAlorsregardaen baslamer....'Alors Il a regardé la mer plus bas.' EnglishThenlooked atdownwardthesea....'Then he looked down at the sea.' (Elision of subject pronoun, contrary to the general rule in other Old French clause structures.)

### Old French

Similarly to Modern French, Old French allows a range of constituents to precede the finite verb in the V2 position.
Il
He
oste
removes.3sg
ses
his
armes
weapons
Il oste ses armes
He removes.3sg his weapons
'He removes his weapons'

### Old Occitan

A language that is compared to Old French is Old Occitan, which is said to be the sister of Old French. Although the two languages are thought to be sister languages, Old Occitan exhibits a relaxed V2 whereas Old French has a much more strict V2. However, the differences between the two languages extend past V2 and also differ in a variation of V2, which is V3. In both language varieties, occurrence of V3 can be triggered by the presence of an initial frame-setting clause or adverbial (1).

## Other languages
### Kotgarhi and Kochi

In his 1976 three-volume study of two languages of Himachal Pradesh, Hendriksen reports on two intermediate cases: Kotgarhi and Kochi. Although neither language shows a regular V 2 pattern, they have evolved to the point that main and subordinate clauses differ in word order and auxiliaries may separate from other parts of the verb:
hyunda-baassie
winter-after
jaa
goes
gõrmi
summer
hõ-i
become-GER
(in Kotgarhi)
hyunda-baassie jaa gõrmi hõ-i
winter-after goes summer become-GER
"After winter comes summer." (Hendriksen III:186)
Hendriksen reports that relative clauses in Kochi show a greater tendency to have the finite verbal element in clause-final position than matrix clauses do (III:188).

### Ingush

In Ingush, "for main clauses, other than episode-initial and other all-new ones, verb-second order is most common. The verb, or the finite part of a compound verb or analytic tense form (i.e. the light verb or the auxiliary), follows the first word or phrase in the clause."
muusaa
Musa
vy
V.PROG
hwuona
2sg.DAT
telefon
telephone
jettazh
striking
muusaa vy hwuona telefon jettazh
Musa V.PROG 2sg.DAT telephone striking
'Musa is telephoning you.'

### O'odham

O'odham has relatively free V2 word order within clauses; for example, all of the following sentences mean "the boy brands the pig":
The finite verb is "'o" and appears after a constituent in the second position.
Despite the general freedom of sentence word order, O'odham is fairly strictly V2 in its placement of the auxiliary verb (in the sentences above, it is ʼo; in the sentences below, it is ʼañ):

### Sursilvan

Among dialects of the Romansh, V2 word order is limited to Sursilvan, the insertion of entire phrases between auxiliary verbs and participles occurs, as in 'Cun Mariano Tschuor ha Augustin Beeli discurriu ' ('Mariano Tschuor has spoken with Augustin Beeli'), as compared to Engadinese 'Cun Rudolf Gasser ha discurrü Gion Peider Mischol' ('Rudolf Gasser has spoken with Gion Peider Mischol'.)
The constituent that is bounded by the auxiliary, ha, and the participle, discurriu, is known as a Satzklammer or 'verbal bracket'.

### Estonian

In Estonian, V2 is very frequent in the literate register but less frequent in the spoken register. When V2 occurs, it is found in main clauses as illustrated in (1).
Kiiresti
quickly
lahku-s-id
leave-PST-3PL
õpilase-d
student-NOM.PL
koolimaja-st.
schoolhouse-ELA
Kiiresti lahku-s-id õpilase-d koolimaja-st.
quickly leave-PST-3PL student-NOM.PL schoolhouse-ELA
'The students departed quickly from the schoolhouse.'
Unlike Germanic V2 languages, Estonian has several instances where V2 word order is not attested in embedded clauses, such as wh-interrogatives (2), exclamatives (3), and non-subject-initial clauses (4).
Kes
who.NOM
mei-le
we-ALL
täna
today
külla
village/visit.ILL
tule-b?

Kes mei-le täna külla tule-b?

'Who will visit us today?'
Küll
EMP

Küll ta täna tule-b.

'S/he's sure to come today!'

come
Täna ta mei-le külla ei tule.
today s/he.NOM we-ALL village/visit.ILL not come
'Today s/he won't come to visit us.'

### Welsh

In Welsh, V2 word order is found in Middle Welsh but not in Old and Modern Welsh, which have only verb-initial order. Middle Welsh displays three characteristics of V2 grammar:
As can be seen in the following examples of V2 in Welsh, there is only one constituent preceding the finite verb, but any kind of constituent (such as a noun phrase NP, adverb phrase AP and preposition phrase PP) can occur in this position.
[$_{DP}$
'r
the
guyrda
nobles
a]
PRT
doethant
came
y gyt.
together.
[$_{DP}$ 'r guyrda a] doethant {y gyt}.
 the nobles PRT came together.
"The nobles came together" → This sentence has a constituent with a subject, followed by the verb in second position.
[$_{DP}$
deu
two
drws
door
a]
PRT
welynt
saw
yn
PRED
agoret.
open.
[$_{DP}$ deu drws a] welynt yn agoret.
 two door PRT saw PRED open.
"They saw two doors that were open" → This sentence has a constituent with a object, followed by the verb in second position.
[$_{AdvP}$
yn
PRED
diannot
immediate
y]
PRT
doeth
came
tan
fire
o
from
r
the

heaven.
[$_{AdvP}$ yn diannot y] doeth tan o r nef.
 PRED immediate PRT came fire from the heaven.
"Immediately there came fire from the heavens" → This sentence has a constituent that is an adverb phrase, followed by the verb in second position.
[$_{PP}$
y
to
r
the
neuad
hall
y]
PRT
kyrchyssant.
went.
[$_{PP}$ y r neuad y] kyrchyssant.
 to the hall PRT went.
"They made for the hall" → This sentence has a constituent that is a preposition phrase, followed by the verb in second position.
Middle Welsh can also exhibit variations of V2 such as cases of V1 (verb-initial word order) and V3 orders. However, these variations are restricted to specific contexts, such as in sentences with impersonal verbs, imperatives, answers or direct responses to questions or commands and idiomatic sayings. A preverbal particle can also precede the verb in V2, but such sentences are limited as well.

### Wymysorys

Wymysory is classified as a West Germanic language but can exhibit various Slavonic characteristics. It is argued that Wymysorys enables its speaker to operate between two word order system, which represent both forces driving its grammar: Germanic and Slavonic. The Germanic system is not as flexible and allows for V2 to exist in it form, but the Slavonic system is relatively free. The rigid word order in the Germanic system causes the placement of the verb to be determined by syntactic rules in which V2 is commonly respected.
Wymysory, like with other languages that exhibit V2, has the finite verb in second position, and a constituent of any category precedes the verb such as DP, PP, AP and so on.
[$_{DP}$
Der
The
klop]
man
kuzt
speaks
wymyioerys.
Wymysorys.
[$_{DP}$ Der klop] kuzt wymyioerys.
 The man speaks Wymysorys.
"The man speaks Wymysorys" → This sentence has a constituent with a subject, followed by the verb in second position.
[$_{DP}$
Dos
This
bihɫa]
book
hot
had
yh
I
gyśrejwa.
written.
[$_{DP}$ Dos bihɫa] hot yh gyśrejwa.
 This book had I written.
"I had written that book" → This sentence has a constituent with an object, followed by the verb in second position.
[$_{PP}$
Fjyr
For
ejn]
him
ej
is
do.
this.
[$_{PP}$ Fjyr ejn] ej do.
 For him is this.
"This is for him" → This sentence has a preposition phrase, followed by the verb in second position.

### Classical Portuguese

V2 word order existed in Classical Portuguese much longer than in other Romance languages. Although Classical Portuguese was a V2 language, V1 occurred more frequently and so it is argued whether or not Classical Portuguese really is a V2-like language. However, Classical Portuguese was a relaxed V2 language, and V2 co-exist with its variations: V1 and V3. Classical Portuguese had a strong relationship between V1 and V2 since V2 clauses were derived from V1 clauses.
In languages where both V1 and V2 exist, both patterns depend on the movement of the verb to a high position of the CP layer. The difference is whether or not a phrase is moved to a preverbal position.
Although V1 occurred more frequently in Classical Portuguese, V2 was more frequently found in matrix clauses. Post-verbal subjects could also occupy a high position in the clause and precede VP adverbs. In (1) and (2), it can be seen that the adverb 'bem' could be before or after the post-verbal subject.
E
and
nos
in-the
gasalhados
welcome
e
and
abraços
greetings
mostraram
showed
os
the
cardeais
cardinals
legados
delegates
E nos gasalhados e abraços mostraram os cardeais legados
and in-the welcome and greetings showed the cardinals delegates
'In the welcome and greetings the cardinal delegates showed this satisfaction well.'
E
and
quadra-lhe
fits-CL.3.DAT
bem
well
o
the
nome
name
de
of
Piemonte...
Piemonte
E quadra-lhe bem o nome de Piemonte...
and fits-CL.3.DAT well the name of Piemonte
'And the name of Piemonte fits it well...'
In (2), the post-verbal subject is understood as an informational focus, but the same cannot be said for (1) because the different positions determine how the subject is interpreted.

## Structural analysis

Various structural analyses of V2 have been developed, including within the model of dependency grammar and generative grammar.

### Dependency grammar

Dependency grammar (DG) can accommodate the V2 phenomenon simply by stipulating that one and only one constituent must be a predependent of the finite verb (i.e. a dependent which precedes its head) in declarative (matrix) clauses (in this, Dependency Grammar assumes only one clausal level and one position of the verb, instead of a distinction between a VP-internal and a higher clausal position of the verb as in Generative Grammar, cf. the next section). On this account, the V2 principle is violated if the finite verb has more than one predependent or no predependent at all. The following DG structures of the first four German sentences above illustrate the analysis (the sentence means 'The kids play soccer in the park before school'):
The finite verb spielen is the root of all clause structure. The V2 principle requires that this root have a single predependent, which it does in each of the four sentences.
The four English sentences above involving the V2 phenomenon receive the following analyses:

### Generative grammar

In the theory of Generative Grammar, the verb second phenomenon has been described as an application of X-bar theory. The combination of a first position for a phrase and a second position for a single verb has been identified as the combination of specifier and head of a phrase. The part after the finite verb is then the complement. While the sentence structure of English is usually analysed in terms of three levels, CP, IP, and VP, in German linguistics the consensus has emerged that there is no IP in German.
The VP (verb phrase) structure assigns position and functions to the arguments of the verb. Hence, this structure is shaped by the grammatical properties of the V (verb) which heads the structure. The CP (complementizer phrase) structure incorporates the grammatical information which identifies the clause as declarative or interrogative, main or embedded. The structure is shaped by the abstract C (complementiser) which is considered the head of the structure. In embedded clauses the C position accommodates complementizers. In German declarative main clauses, C hosts the finite verb. Thus the V2 structure is analysed as
    1 Topic element (specifier of CP)
    2 Finite-verb form (C=head of CP) i.e. verb-second
    3 Remainder of the clause
In embedded clauses, the C position is occupied by a complementizer. In most Germanic languages (but not in Icelandic or Yiddish), this generally prevents the finite verb from moving to C.
    The structure is analysed as
       1 Complementizer (C=head of CP)
       2 Bulk of clause (VP), including, in German, the subject.
       3 Finite verb (V position)
This analysis does not provide a structure for the instances in some language of root clauses after bridge verbs.
    Example: Danish Vi ved at denne bog har Bo ikke læst with the object of the embedded clause fronted.
    (Literally 'We know that this book has Bo not read')
The solution is to allow verbs such as ved to accept a clause with a second (recursive) CP.
    The complementizer occupies C position in the upper CP.
    The finite verb moves to the C position in the lower CP.
