List of English irregular verbs

For details about the types and origin of irregular verbs in English, see English irregular verbs. For verbs generally, see English verbs.

This is a list of irregular verbs in the English language.

For each verb listed, the citation form (the bare infinitive) is given first, with a link to the relevant Wiktionary entry. This is followed by the simple past tense (preterite), and then the past participle. If there are irregular present tense forms (see below), these are given in parentheses after the infinitive. (The present participle and gerund forms of verbs, ending in -ing, are always regular. In English, these are used as verbs, adjectives, and nouns.) In the case of modal verbs the present and preterite forms are listed, since these are the only forms that exist.

The right-hand column notes whether the verb is weak or strong and whether it belongs to a subclass, and links to descriptions elsewhere. Information about the development of these verbs generally can be found at English irregular verbs; details of the etymology and usage of specific verbs can be found by consulting Wiktionary.

In some cases, there are two or more possibilities for a given form. In the table, the preferred or more common usage is generally listed first, though for some words the usage is nearly equal for the two choices. Sometimes the usage depends on the dialect. In many cases, such as spell (spelt vs. spelled), learn (learnt vs. learned), and spill (spilt vs. spilled), American English normally uses the regular form, while British English tends to favor the irregular. In other cases, such as dive (dived vs. dove) and sneak (sneaked vs. snuck), the opposite is true. Australian, New Zealand and South African English tend to follow the British practice, while Canadian English often sides with the American usage.

The table includes selected archaic forms, marked * (some of these forms may survive in dialectal or specialist uses).

Present tense irregular verbs

Though the list of verbs irregular in the preterite or past participle is long, the list of irregular present tense verbs is very short. Excepting modal verbs like "shall", "will", and "can" that do not inflect at all in the present tense, there are only four (only two if pronunciation is ignored):

be: I am, you are, he is, we are, they are.
do (and compounds such as "undo" and "redo"): I do, you do, he does, we do, they do where "does" is pronounced /ˈdʌz/ in contrast to /ˈduː/, the pronunciation of the infinitive and the other present tense forms.
have: I have, you have, he has, we have, they have.
say (and compounds such as "gainsay" and "naysay"): I say, you say, he says, we say, they say where "says" may be, dependent on regional accent, pronounced /ˈsɛz/ as opposed to /ˈseɪz/ in the manner of the infinitive and the other present tense forms.
