A finite verb (sometimes called main verbs) is a verb that has a subject, this means that it can be the main verb in a sentence. It shows tense (past / present… etc) or number (singular / plural).
My brother kicked the ball.
(My brother is the subject – kicked describes what the subject does – kick is a finite verb).
A non-finite verb has no subject, tense or number. The only non-finite verb forms are the infinitive (indicated by to), the gerund or the participle.
