The subject and the verb must agree, both must be singular or both must be plural. Problems arise in the present tense because an -s /-es must be added at the end of the verb when the subjects performing the action is a singular third person: he, she, it or words they could substitute.
Let’s see the following example for clarity.
- The third person singular form of the regular verb has -es at the end. The other verbs are alike.
- When the subject of a sentence is composed of two or more pronouns connected by and use plural verb.

- When two or more singular nouns and pronouns are connected by or OR nor, use a singular verb.
The book or the cassette is in the shelf
- When the compound subject contains both singular and plural noun and pronoun joined by or OR nor, the verb should agree with the subject nearer to the verb
The girl or her friends dance every weekend.
Her friends or the girl dances every weekend.
- Doesn’t/does not should be used only with singular subject.
He doesn’t like to miss any class.
- Don’t/do not should be used with plural subject alone.

- When a phrase comes between subject and the verb, the verb agrees with the subject and not the noun or pronoun in the phrase.
