This document discusses linking verbs and their uses in sentences. Linking verbs connect the subject of a sentence to a predicate noun or adjective without showing physical action. When connected to a noun, the noun identifies what the subject is, and when connected to an adjective, the adjective describes the subject. Some common linking verbs are forms of "to be" like is, are, was as well as seem, look, smell, and taste. Memorizing the list of linking verbs is important.
