These two independent clauses can be combined with a comma and a coordination conjunction or a semicolon. The agreement means that the parts of sentences match. Subjects must agree with verbs, and pronouns must correspond to precursors. Singular subjects need singular verbs; Plural subjects need plural abdelle. All parts of the English language are used to form sentences. All sentences contain two parts: the subject and the verb (this is also called the predicate). The subject is the person or thing that does something or is described in the sentence. The verb is the action that the person or thing performs, or the description of the person or thing. If a sentence has no subject or verb, it is not a complete sentence (for example. B in the sentence “Go to bed”, we do not know who went to bed).
