Finite verb

From Wikipedia, the free encyclopedia

A finite verb is a verb that is inflected for person and for tense according to the rules and categories of the languages in which it occurs. Finite verbs can form independent clauses, which can stand by their own as complete sentences.

In most Indo-European languages, every grammatically correct sentence or clause must contain a finite verb; sentence fragments not containing finite verbs are described as phrases. In Latin and some Romance languages, however, there are a few words that can be used to form sentences without verbs, such as Latin ecce, Portuguese eis, French voici and voilà, and Italian ecco, all of these translatable as here ... is or here ... are. Some interjections can play the same role. Even in English, a sentence like Thanks for your help! has an interjection where it could have a subject and a finite verb form (compare I appreciate your help!).

In English, as in most related languages, only verbs in certain moods are finite. These include:

the indicative mood (expressing a state of affairs); e.g., "The bulldozer demolished the restaurant," "The leaves were yellow and stiff."
the imperative mood (giving a command).
the subjunctive mood (expressing something that might or might not be the state of affairs, depending on some other part of the sentence); nearly extinct in English.

Verb forms that are not finite include:
