Final answer:
The simple predicate in a sentence is synonymous with the verb. It represents the action or state of the subject without any additional words or modifiers. Subject-verb agreement is crucial, where singular subjects take singular verbs, and plural subjects take plural verbs.
Step-by-step explanation:
The simple predicate in a sentence is the same thing as the verb. The simple predicate indicates the action, occurrence, or state of being expressed in the sentence. It is the main part of the predicate in a sentence. Unlike the complete predicate, which includes the verb and all the words related to it, the simple predicate is only the verb or verb phrase itself.
The subject of a sentence, on the other hand, is who or what the sentence is about. The subject and verb must agree in number, which means a singular subject requires a singular verb, while a plural subject needs a plural verb.
For example, in the sentence, 'The bus leaves in five minutes,' 'bus' is the subject, and 'leaves' is the simple predicate. Likewise, in 'The buses leave in five minutes,' 'buses' is the subject, and 'leave' is the simple predicate.
