What is the main function of a verb in a sentence?

The main function of a verb in a sentence is to show action or a state of being. Verbs are essential components of sentences, as they convey what the subject is doing or experiencing. This action can be physical, such as "run" or "jump," or it can refer to a state of being, such as "is" or "become."

Understanding verbs is fundamental because they not only indicate actions but also help define the relationship between subjects and their predicates, providing clarity and context to the overall meaning of the sentence. This characteristic distinguishes verbs from other parts of speech, as their primary role centers on action or existence.
