Finite Verb vs. Nonfinite Verb: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 24, 2023
Finite verbs change form based on subject and tense, whereas nonfinite verbs don't exhibit such changes.

Key Differences

Finite verbs are verbs that have a specific tense, number, and person. They can act as the main verb in a sentence and change forms according to the subject's number and person. For instance, in the sentence "She sings," "sings" is a finite verb agreeing with its third-person singular subject. In contrast, nonfinite verbs do not change form based on tense, number, or person. They can't stand alone as the main verb without an auxiliary.
Nonfinite verbs come in three primary forms: infinitives, gerunds, and participles. For example, in "To read is fun," "to read" is an infinitive and a nonfinite verb. The characteristic that sets nonfinite verbs apart is their inability to dictate the number or person of the subject. On the other hand, finite verbs will always indicate a specific time, whether it's past, present, or future, by their form.
In many sentences, finite verbs and nonfinite verbs can appear together. Consider "She wants to dance." Here, "wants" is a finite verb because it changes based on the subject and tense, while "to dance" is a nonfinite verb in the infinitive form. The finite verb provides the primary action or state of the subject, while the nonfinite verb often provides additional information or context.
Understanding the difference between finite verbs and nonfinite verbs is crucial for mastering English grammar. Recognizing a finite verb helps in determining the sentence's tense and agreement, while nonfinite verbs are essential for constructing various verb forms and adding depth or detail to sentences.
