A finite verb anchors a clause: it may show tense or be a modal such as can. Non-finite forms do not show tense on their own or change to agree with a subject. An infinitive uses the base form, with or without to. A gerund uses -ing to name an activity. Present participles end in -ing; past participles may end in -ed or have irregular forms such as broken and written. Participles can describe nouns or combine with helping verbs.
