What is the function of a verb in a sentence?

The role of a verb in a sentence is to represent an action or a state of being. Verbs are essential components of sentences as they convey what the subject is doing (in the case of action verbs, like "run" or "think") or the condition of the subject (in the case of state of being verbs, like "is" or "seem"). Without a verb, a sentence would lack a crucial element that provides meaning and allows for expression of complete thoughts.

In contrast to this, the other functions indicated by the other options do not capture the primary role of a verb. While some verbs can interact with adjectives or connect phrases within more complex structures, their fundamental purpose remains action or state of being representation.
