There are mainly two types of verbs in English – finite and non-finite. Finite verbs change their forms when there is a change in the number or person of the subject. Finite verbs also have different forms in different tenses.

Non-finite verbs do not change their form when the number or person of the subject changes. There are mainly three types of non-finite verbs: infinitives, gerunds and participles.
