Step-by-step explanation:
A verb or verb phrase is the part of a sentence that expresses the action, occurrence, or state of being.
Verbs can be either action verbs, which show action (e.g., run, jump), or linking verbs, which connect the subject to the complement (e.g., is, seem).
A verb phrase consists of a main verb and any auxiliary verbs that are used to express tense, aspect, or mood (e.g., have been walking).
