Other verbs link the subject with a word or words in the predicate and are called linking verbs. An action verb is transitive when it is followed by a noun or pronoun that tells who or what receives the action. The word that receives the action is called the direct object. An action verb without a direct object is intransitive. Singular subjects must take singular verbs.
Plural subjects take plural verbs.
The tense of a verb tells whether something happened in the past, is happening in the present, or will happen in the future. Both action verbs and linking verbs show tense and time. An adverb is a word that modifies or describes a verb, an adjective, or another adverb. An adverb tells when, where, or how the action takes place. Use adverbs as modifiers to make sentences more descriptive.
