Final answer:
The subject and verb in a sentence must agree in standard English grammar.
Step-by-step explanation:
The subject of a sentence names something. The predicate contains the verb, which expresses an action, an occurrence, or a state of being. The subject and verb in a sentence must agree. In standard English, "agreement" means that a singular subject must have a singular verb (The bus leaves in five minutes) and a plural subject must have a plural verb (The buses leave in five minutes). However, some English dialects omit the -s ending for singular verbs or use a singular verb with a plural subject: The man ask for help. Property taxes was raised last year.
