A nonfinite verb is one of the most important grammar concepts in English, yet it often confuses learners because it does not behave like a regular verb.
Unlike finite verbs, a nonfinite verb does not show tense, person, or number.
Instead, it functions as a noun, adjective, or adverb while still expressing an action or state.
Understanding the nonfinite verb is essential for writing clear, natural, and grammatically correct English.
If you’re a student, teacher, writer, or English learner, knowing the meaning, types, usage, and examples of nonfinite verbs will help you build better sentences.
This guide explains everything in simple English with tables, examples, grammar rules, common mistakes, and FAQs.
Quick Answer
A nonfinite verb is a verb form that does not show tense, person, or number.
The three main types of nonfinite verbs are infinitives, gerunds, and participles.
What Is a Nonfinite Verb?
A nonfinite verb is a verb that does not act as the main verb of a sentence. It does not change according to the subject or tense.
Examples
- She wants to travel.
- Reading improves vocabulary.
- The broken window needs repair.
In these sentences:
- to travel = infinitive
- reading = gerund
- broken = participle
All are nonfinite verbs.

Why Do People Confuse Nonfinite Verbs?

- Continuous tense verbs
The sentence determines their function.
