Infinite Verbs: Conjugating the Unending
By Mohamed IDBRAHIM - October 9, 2026 - 4 min read
Introduction
Have you ever seen a verb that never seems to change? In English, infinite verbs (often called non-finite verbs) are verb forms that do not show tense, person, or number. They are the unending, unchangeable core of many sentences, and mastering them will make your English sound more natural and fluent.
Definition
An infinite verb is a verb form that does not function as the main verb of a clause and is not limited by subject or tense. The three main types are infinitives (to go, to eat), gerunds (going, eating), and participles (gone, eaten, going). Unlike finite verbs, which change with the subject (I go, she goes), infinite verbs stay the same no matter who or when.
For example:
- Finite: She writes a letter. (changes with subject and tense)
- Infinite: She wants to write a letter. (never changes)

FAQ
Q1: What is the difference between an infinitive and a gerund? A1: An infinitive is "to + verb" (to run), while a gerund is the -ing form used as a noun (running). Some verbs take only one, some take both with a change in meaning.
Q2: Can infinite verbs have tense? A2: No, they do not show tense. However, they can show aspect (perfect: to have gone) and voice (passive: to be eaten).
Q3: Why are they called "infinite"? A3: The term comes from Latin "infinitivus," meaning "unlimited." Unlike finite verbs, they are not limited by subject or tense.
