Verbs : - These are words that refer to an action or a state of being. A sentence must have a verb or else it is incomplete. Along with nouns, verbs are the main part of a sentence or phrase, telling a story about what is taking place. In fact, without a verb, full thoughts can’t be properly conveyed, and even the simplest sentences, such as Maria sings, have one. Actually, a verb can be a sentence by itself, with the subject, in most case you, implied, such as, Sing! and Drive!

Example : - She eats chocolate cake on Sundays . Here , eats is a verb as it tells about the action performed by noun or pronoun .

Irregular Verbs : - Verbs that do not have -ed, -en or -t as suffix in their past and past participle form are called irregular or strong verbs. catch and go have their past forms as caught and went and not the usual -ed or -en or -t in their past tense forms.

For Example: You should have seen Akash’s face when she got him surprise. Here , seen is a irregular verb as it has different past participle form . Seen is the third form of main verb see .
