Linking verbs connect the subject to a subject complement, a word or word group that completes the meaning of the subject by renaming or describing it.
When the simple subject complement renames the subject, it is a noun or noun equivalent (sometimes called a predicate noun), such as scam. When it describes the subject, it is an adjective or adjective equivalent (sometimes called a predicate adjective), such as mild.
Linking verbs are usually a form of be: be, am, is, are, was, were, being, been. Verbs such as appear, become, feel, grow, look, make, prove, remain, seem, smell, sound, and taste are linking when they are followed by a word group that names or describes the subject.
