Most verbs have three or four inflected forms in addition to the base form: a third-person singular present tense form in "-(e)s" ("writes", "botches"), a present participle and gerund form in "-ing" ("writing"), a past tense ("wrote"), and – though often identical to the past tense form – a past participle ("written"). Regular verbs have identical past tense and past participle forms in "-ed", but there are 100 or so irregular English verbs with different forms (see list). The verbs "have", "do" and "say" also have irregular third-person present tense forms ("has", "does" , "says" ). The verb "be" has the largest number of irregular forms ("am, is, are" in the present tense, "was, were" in the past tense, "been" for the past participle).
