A negative verb or negation verb is a type of auxiliary that is used to form the negative of a main verb. The main verb itself has no personal endings, while the negative verb takes the inflection. The English auxiliary don't/doesn't performs a similar function by acting as a negative verb that indicates whether one or multiple individuals are involved while the verb referring to the negated activity remains uninflected, e.g. "he cares"/"we care" versus "he doesn't care"/"we don't care."

The negative verb is typical of the Uralic languages. Uralic languages inflect by person, thus one word, the negative verb corresponds to e.g. "I don't" (Finnish en) or "doesn't" (ei).
The negative verb is conjugated in moods and personal forms in Finnish. In the present tense, the form of the main verb is just the stem of the present form without a personal ending, e.g. lähden – en lähde ("I leave" – "I do not leave"), menisit – et menisi ("you would go" – "you would not go"), syönee – ei syöne ("he/she may eat" – "he/she may not eat"), ottakaamme – älkäämme ottako ("let's take" – "let's not take"). In the imperfect tense, the form of the main verb is the past participle, e.g. otin – en ottanut ("I took" – "I did not take"), otimme – emme ottaneet ("we took" – "we did not take").

Hungarian has lost most evidence of a negative verb, but the negation particle nem becomes ne before verbs in the jussive/imperative (also sometimes called the conditional mood, or J-mood).
Furthermore, the 3rd person present indicative of the copular verb (lenni) has unique negative forms nincs(en) and nincsenek as opposed to nem van and nem vannak, but only when the particle and verb would occur adjacently. In all other instances the copular verb acts regularly. These forms are also unique in that they have an existential role "there is (not)" and "there are (not)". In the present indicative 3rd person, copular verbs are not used; rather the absence of a verb (with or without a negation particle) implies the copula.
The basic pattern is u becomes anai.

- The nai ending conjugates in two ways.
- As an i adjective. For example the past tense of tabenai is tabenakatta and the te form is tabenakute.
- There is a special te form made by adding de. For example, tabenaide. This is used, for example, in tabenaide kudasai: "Please don't eat (this)".

For any verbs, adding a 不(bu)in the front means not doing this verb. E.g 吃(chi) eat The negative verb would be 不吃 (bu chi). 看(kan) look/watch 不看（bu kan） 坐（zuo）sit 不坐（bu zuo) Note: This form is more used to express the unwillingness of the subject to carry out the verb, or say used for unhappened cases. For things that has already happened or not happened, replace the 不 with 没(mei)．
The negative mood in Kannada is conjugated by adding the PNG (Person-Number-Gender) marker to the root without a tense marker. It is occasionally used in common speech conjugated, usually with a few common defective verbs in the Negative Mood. e.g. ಸಾಲದು (saaladu) - It is not sufficient, ಕೂಡದು (kUDadu) - It is not fitting (Not possible / Should not) However, it is very often used in negative adjectives derived from verbal roots' participial forms.
