A linking verb is a verb that connects the subject of a sentence to a subject complement (a noun, pronoun, or adjective that renames or describes the subject). Unlike action verbs, linking verbs do not show action. Instead, they link the subject to the rest of the sentence. Common linking verbs include "is," "am," "are," "was," "were," "seem," "appear," "become," and "feel."
By understanding and recognizing linking verbs, you can improve your sentence structure and create more descriptive and accurate sentences.
