Linking Verbs link the subject of a sentence to a noun or an adjective in the predicate.

Common linking verbs include: am, is, are, was, were, will be.

The verbs seem, feel, appear, look, and taste can also be used as linking verbs.

Subjects and linking verbs must agree.

The noun that follows a linking verb renames or identifies the subject.

the adjective that follows a linking verb describes the subject. It's called the Predicate Adjective.
