In languages such as English, in which verbs are conjugated, regular verbs are conjugated in a regular or consistent way, while irregular verbs do not follow an obvious pattern in their conjugation. For example, in English the way to conjugate a regular verb is to add -ed to the past tense, and -ed to the past participle, e.g. "to kick" kick (present tense), kicked (past tense), and (had) kicked (past participle, i.e. "he had kicked him"). Irregular verbs, which are the ones which are used most often in English do not show this pattern. Examples are "sing, sang, sung" and "think, thought, thought." An especially irregular verb in English is "to be" which has the forms "is, was, (had) been," and the present tense of this verb is also irregular in person and number, e.g. "I am, you are, he/she is, we are, you are, they are." Most verbs do not show any difference between the 1st person ("I"), and the second person ("you") in the verb forms. The verb "to go" is also quite irregular, "go, went, gone." Most verbs in European languages show this distinction between irregular and regular verbs.
You never chose whether or not you are going to use a verb or irregular verb. Look at what you are trying to say, then pick the verb that fits the sentence. The verb may or may not be irregular.
An irregular verb is a verb that took place before or after the present and should not have a suffix such as -ed or -d. An example of an irregular verb could be "spoken" if used in a statement referring to the present.
In English, the subject and the verb must agree, so if you have a plural subject (noun or pronoun), you would use a plural verb. Fortunately, most of the verbs in English do not have a special ending for use with a plural subject: I carry my books to school; they carry their books to school. Notice the verb remains the same ('carry'), even though the subject (I, which is singular, or they, which is plural) changed.
You only have to worry about agreement of subject and verb when using helping verbs like "to have" or when using state of being verbs like "to be." And there is one other place where you will see changes occur: the third person singular form of most present tense regular verbs has an -s ending.
Some examples: The boy is happy. (One boy, singular; singular verb, is.) The boys are happy (More than one-- plural noun; thus, plural verb, are.) The girl has a book. The girls have some books. The man walks to work on Thursday. The men walk to work on Thursday.
As mentioned earlier, with most present tense verbs, they have no ending changes: I love ice cream. We love ice cream. They love ice cream. (The only verb ending is the -s on the 3rd person: Maria loves ice cream.) So, to sum up: plural verbs are used with a plural subject, and on a few occasions, you will have to either change the entire verb (has/have; is/are; was/were) so that it can agree with the subject, or change the ending of the (present tense) verb to make it agree with the subject.
