## Finnish
### Etymology

The indicative forms are from Proto-Finnic *e-, from Proto-Uralic *e- ~ *ä- ~ *a- (negative verb stem). The imperative forms are from Proto-Finnic *älä-, from the Proto-Finno-Ugric negative imperative verb stem *älä-.
Noteworthy forms include eivät (pro earlier evät, reformed after ei). For more forms, see the Proto-Finnic and Proto-Uralic pages.
Cognates for the indicative forms include Estonian ei, Karelian ei, Livonian ä’b, Veps ei, Northern Sami ii, Skolt Sami ij, Erzya а- (a-), э- (e-), и- (i-), Eastern Mari ы- (y-), Udmurt уг (ug), Komi-Zyrian оз (oz), Northern Mansi [script needed] (ä-), Forest Enets [script needed] (i-) and Northern Selkup [script needed] (aša) (Taz). Cognates for the imperative forms include Estonian ära, Northern Sami ale, Kildin Sami ель (jel’), Erzya иля (iľa).
Not related to Swedish ej, Icelandic ei, Old Norse eigi, despite the similarity; the Finnic and Norse terms are false cognates.

### Pronunciation

* IPA: /ˈei̯/, [ˈe̞i̯]
* Audio:(file)
* Rhymes: -ei
* Hyphenation: ei

### Verb

ei (third-person singular indicative)
* (auxiliary) The negative verb or negation verb; not, be not, do not, etc. [with connegative]
    En ole käynyt siellä. ― I have not been there.
    Hän ei ole kotona. ― She isn't home.
    Etkö tiedä? ― Don't you know?
    Älä koske siihen! ― Don't touch that!

#### Usage notes

* With certain conjunctions, contractions may be used (e.g. miksi + ei → miksei). In some cases, like ellei and jollei, the independent conjunction has fallen out of use, but the contractions still remain in use. For other cases, the contractions are optional, but commonly used. When the contraction is used, the negative verb may effectively shift ahead in the clause:
    En tiedä, miksi hän ei tullut. → En tiedä, miksei hän tullut. I don't know why he didn't come.
* The negation verb is used with the connegative form of the main verb.
* In the active voice, the verb ei is inflected in person and mood (only for imperative, otherwise the indicative forms are used).
** In the indicative mood and present tense (including for olla in the perfect tense), the connegative form is identical to the second-person singular imperative.
** In the indicative mood and past tense (including for olla in the pluperfect tense and the main verb in the perfect and pluperfect tenses), the connegative form is the past active participle (-nut / -nyt).
** In the conditional and potential moods, the connegative ends with the mood markers -isi- and -ne- (without the personal ending), respectively.
** In the imperative mood, the connegative form is the same as the positive form for the second-person singular, while for the other forms a form ending in -ko / -kö is used.
* In the passive voice, the third-person singular ei (or älköön for the imperative mood) is used.
** In the present tense, the connegative form is the impersonal or passive form without the final -an / -än (indicative), -in (conditional), -en (potential) and -on / -ön (imperative).
** In the past tense (including the perfect and pluperfect tenses), the connegative form is the past passive participle (-ttu / -tty).
* The total object in the negative is always in the partitive case, not the accusative case (whether that be the nominative, genitive or a special form):
    Näen koiran. → En näe koiraa. ― I see a dog. → I don't see a dog. (accusative → partitive)
    Näen naiset. → En näe naisia. ― I see the women. → I don't see the women. (accusative → partitive)
    Näen sinut. → En näe sinua. ― I (can) see you. → I don't see you. (accusative → partitive)
* Indicative:
   * Hän näkee. → Hän ei näe. He sees. / He does see. → He doesn't see.
   * Hän näki. → Hän ei nähnyt. He saw. / He did see. → He didn't see.
   * Hän on nähnyt. → Hän ei ole nähnyt. He has seen. → He hasn't seen.
   * Hän oli nähnyt. → Hän ei ollut nähnyt. He had seen. → He hadn't seen.
* Conditional:
   * Hän näkisi. → Hän ei näkisi. He would see. → He wouldn't see.
   * Hän olisi nähnyt. → Hän ei olisi nähnyt. He would have seen. → He wouldn't have seen.
* Imperative:
   * Näe! → Älä näe! See! → Don't see!
* Potential:
   * Hän nähnee. → Hän ei nähne. He probably sees. → He probably doesn't see.
   * Hän lienee nähnyt. → Hän ei liene nähnyt. He probably has seen. → He probably hasn't seen.
* Indicative:
   * Hänet nähdään. → Häntä ei nähdä. He is seen. → He isn't seen.
   * Hänet nähtiin. → Häntä ei nähty. He was seen. → He wasn't seen.
   * Hänet on nähty. → Häntä ei ole nähty. He has been seen. → He hasn't been seen.
   * Hänet oli nähty. → Häntä ei ollut nähty. He had been seen. → He hadn't been seen.
* Conditional:
   * Hänet nähtäisiin. → Häntä ei nähtäisi. He would be seen. → He wouldn't be seen.
   * Hänet olisi nähty. → Häntä ei olisi nähty. He would have been seen. → He wouldn't have been seen.
* Imperative (the second form, perfect imperative, is rare):
   * Nähtäköön! → Älköön nähtäkö! Let (it) be seen! → Don't let (it) be seen!
   * Oltakoon nähty! → Älköön oltako nähty. Let (it) have been seen! → Don't let (it) have been seen!
* Potential:
   * Hänet nähtäneen. → Häntä ei nähtäne. He probably is seen. → He probably isn't seen.
   * Hänet lienee nähty. → Häntä ei liene nähty. He probably has been seen. → He probably hasn't been seen.

#### Conjugation

* The negation verb has no infinitive form.
* Indicative, conditional and potential moods use the indicative forms (stem e-), for which the verb is conjugated only in person (the moods are distinguished by the connegative form used).
* In the imperative mood the negation verb has the stem äl-. As with all verbs, the first-person plural imperative is formal or dated, while the third-person imperative (both singular and plural) is dated.
* An archaic optative mood exists and is used mainly in poetry.

#### Usage notes

* ei is a defective verb: It is only inflected for person, and has a distinct imperative series.
* In the indicative, conditional, imperative and potential used with a connegative form of the main verb:
** In the present indicative the connegative is formally identical to the imperative singular:
    hää ei taho ― she doesn't want
    höö evät taho ― they don't want
** In the imperfect indicative, the connegative is formally identical to the past active participle (placed in the nominative singular in the singular, nominative plural in the plural):
    hää ei tahtont ― she didn't want
    höö evät tahtoneet ― they didn't want
** In the conditional the connegative is formally identical to the third-person singular conditional form:
    hää ei tahtois ― she wouldn't want
    höö evät tahtois ― they wouldn't want
** In the imperative, the connegative is formed by replacing the imperative endings of the verb by the element -ko:
    hää elköö tahtoko! ― may she not want!
    höö elkööt tahtoko! ― may they not want!
** The second-person singular of the imperative takes a distinct connegative, which is formally identical to the present indicative connegative:
    elä taho! ― do not want!
** In the potential, the connegative is formed by replacing the connegative endings of the verb by the element -ne:
    hää ei tahtone ― she probably won't want
    höö evät tahtone ― they probably won't want
* For the impersonal forms, the third-person singular (ei / elköö) is used together with an impersonal connegative:
    ei tahota ― it isn't wanted
    ei tahottu ― it wasn't wanted
    ei tahottais ― it woudn't be wanted
    elköö tahottako ― may it not be wanted
    ei tahottane ― it probably won't be wanted
* When used to negate an infinitive, adverb, noun, etc., the negative verb agrees with the subject of the sentence:
    hää herviijaa ei ehtiä ― he is afraid to not make it in time
    höö herviijaat evät ehtiä ― they are afraid to not make it in time

** 18th century, Wil Hopcyn, “Bugeilio’r gwenith gwyn”:
    Myfi’n bugeilio’r gwenith gwyn, Ac arall yn ei fedi.Me watching the white wheat, And another reaping it.
* her, it (with reference to masculine nouns; as object of a verbal noun; triggers aspirate mutation of following consonant and h-prothesis of a following vowel)
** Traditional, “Milgi, milgi”:
    Ar ben y bryn mae sgwarnog fach, ar hyd y nos mae'n pori A’i chefen brith a’i bola bola gwyn yn hidio dim am filgi.On top of the hill there's a little hare, all night long she grazes With her speckled back and her white white belly without taking any heed of any greyhound.

##### Usage notes

* In formal Welsh, masculine ef or feminine hi is added after the noun or verbnoun which ei precedes to indicates emphasis on the determiner or pronoun. In colloquial Welsh, the masculine takes e or o (southern and northern forms respectively) after a consonant and fe or fo (southern and northern) after a vowel, whereas the feminine takes hi, but is not necessarily an indicator of emphasis. Here, it is often included with the determiner and always included with the pronoun. The exception to the latter case is in passive constructions employing cael, where no addition is found.
* In formal Welsh, the contraction 'i is a valid form of ei found after mostly functional vowel-final words. In colloquial Welsh, ei is often contracted to 'i after almost any vowel-final word. The exception is both forms of the language is after the preposition i (“to, for”), after which ei contracts to 'w. (Contraction to 'w after wedi is sometimes encountered but considered non-standard.)
* Pronomial ei and 'i can occur before any verbal noun. Before a verb, pronomial 'i is found only in formal language after certain vowel-final preverbal particles. See entry for 'i for more information.
* The colloquial pronunciation /iː/, /ɪ/ is the original pronunciation, as shown by the Middle Welsh form y. The more careful pronunciation /ei̯/ is a later spelling pronunciation.

## Ye'kwana
### Pronunciation

* IPA: [ej]

### Etymology 1
#### Verb

ei
* (intransitive, agentive) to be

##### Usage notes

Many forms of this verb are irregular. Some are based on a root ei ~ e', some on a ~ aa, some on a'ja, and some on ööne ~ wene:
* ei ~ e' is used with most tense/aspect/mood markers and all adverbial and nominal derivatives of the verb.
* a ~ aa is used for the nonpast form, question forms, and two third-person forms na'ñojo and naichü.
* a'ja is used for past imperfectives.
* ööne ~ wene is used for the permanent aspect; this is the only verb in the language that has such an aspect.
The verb also takes an irregular suffix -ya in place of the ordinary recent/distant past perfective suffix -i. Similarly, the plural form of the same suffix is -yato rather than -icho.
This verb can be used as an auxiliary to form various constructions, making it possible to express tense/aspect/mood for constructions made with non-finite verb forms by putting the relevant markers on the copula instead.

### Etymology 2
#### Verb

ei
* (transitive) to seek, to look for
