Nonfinite verb

A nonfinite verb, in contrast to a finite verb, is a derivative form of a verb that lacks inflection (conjugation) for number or person. In the English language, the nonfinite verb cannot perform action as the main verb of an independent clause, while in French, the first verb is typically the only finite one. In English, nonfinite verbs include infinitives, participles and gerunds. Nonfinite verb forms in some other languages include converbs, gerundives and supines. The categories of mood, tense, and or voice may be absent from non-finite verb forms in some languages.

Because English lacks most inflectional morphology, the finite and the nonfinite forms of a verb may appear the same in a given context.
