Is has is action verb or a linking verb?

Answer 1

Is is a linking verb also known as a copulative verb. It can connect two nominative nouns such as "God is love." Used in metaphors as when Jesus said of the unleavened bread, "This is my body", the verb is can have the sense "this means my body", or "this represents my body." The verb become is another good example of a linking verb.

Answer 2

"Is" can serve as both an action verb and a linking verb. As an action verb, it signifies an action being performed. As a linking verb, it connects the subject of a sentence to a noun, pronoun, or adjective that describes or renames the subject.
