Some of the verbs are totally different that they donot follow the rules of suffix or prefix and donot share any similarities with the parent word or root and are called as irregular verbs.

The following is a list of 204 irregular verbs that are commonly used in standard modern English. It omits many rare, dialectal, and archaic forms, as well as most verbs formed by adding prefixes to basic verbs (unbend, understand, mistake, etc.). It also omits past participle forms that remain in use only adjectivally (clad, sodden, etc.). For a more complete list, with derivations, see List of English irregular verbs. Further information, including pronunciation, can be found in Wiktionary. The list that follows shows the base, or infinitive form, the past tense and the past participle of the verb.
