English verbs

Regular verbs in English have four forms:

• the base, which is equivalent to the infinitive without 'to' and most forms of the present tense (for example, wâit, to wâit, Î wâit) (The accents, which are not part of the language, are included to show stress and pronunciation: see English spellings for a table and English phonemes for the IPA. Words in italics suggest meaning, and an equals sign is placed between homophones)
• the -s form, which is used for the third person singular of the present tense (hê wâits, shê wâits)
• the -íng form, used for the present participle and gerund (Î'm wâiting, wâiting ís bŏring; in most cases the base sheds any final e: compare sínging sing with síngeing singe, pronounced *sínjing)
• the past form, which is used both for the past tense and the past participle, and which consists of adding -ed to the base (from wâit, I wâited, shê has wâited, *wâitid; from loòk, loòked *lùkt; from sêem, sêemed *sêemd), or, in the case of verbs ending in -e, -d only (from fâde, fâded *fâidid)

Irregular verbs also have these forms, and form the -s and -ing forms regularly: béar, béars, béaring. But the past tense and/or past participle are not formed regularly: to béar has the principal parts béar, bŏre, bŏrn, which means that there is no form *beared; instead, an example of the past tense is shê bŏre hím and of the past passive hê was bŏrn.
