English irregular verbs

Verbs with less common conjugations in English

The English language has many irregular verbs, approaching 200 in normal use—and significantly more if prefixed forms are counted. In most cases, the irregularity concerns the past tense or the past participle. The other inflected parts of the verb—the third person singular present indicative in -[e]s, and the present participle and gerund form in -ing—are formed regularly in most cases. There are a few exceptions: the verb be has irregular forms throughout the present tense; the verbs have, do, and say have irregular -[e]s forms; and certain defective verbs lack most inflection.
