Linking verbs are verbs that describe the subject rather than the action like other verbs. With linking verbs like be, become, or seem, the action in the sentence is merely existing.
In contrast to other verbs, linking verbs describe the subject rather than the action. When a phrase contains a connecting verb like be, become, or appear, there is no actual activity taking place.
Subject complements, which provide information on the sentence's subject, are used with linking verbs. Adjectives (predicate adjectives) or nouns (predicate nominatives/predicate nouns) can be used as subject complements.
Searching for the subject complement is the quickest approach to spot linking verbs, although this might be complicated. Try to identify whether the verb is describing an action (action verb) or the condition of the subject if you're having problems (linking verb).
