A verb is one of the main parts of a sentence in English language. The verb signals an action, an occurrence or a state of being. There are two kinds of verbs, main (or lexical) verbs and helping (or auxiliary) verbs. Main verbs have a meaning of their own, for example, talk, sing, write, etc. Helping verbs do not have a meaning of their own and they accompany a main verb to help express tense, voice or mood, for example, is, am, was, etc.
Main verbs are of two types: Transitive verbs that always have direct objects; meaning someone or something receives the action of the verb. Example: He ate the pie. (the pie – direct object); and intransitive verbs that are not followed by any direct object. Example: My foot hurts.
Verbs can also be divided as strong (or irregular) verbs and weak (or regular) verbs. A strong (or irregular) verb is one that does not take on the regular spelling patterns of simple past tense and past participle verbs, example: cut. A weak (or regular) verb is one that forms its simple past tense and its past participle by adding –ed or –d to the base form of the verb, example: call – called.
