Linking verbs are verbs that don’t show action but rather describe the subject.
A linking verb explains the state of the subject, for example, what it is or how it looks, without showing any action.
All verbs can be put into two groups, action verbs and linking verbs. However, sometimes a verb can be either, depending on how it’s used.
A linking verb describes the subject as a whole or adds more detail about it. A sensory verb, for example, looks, feels, smells, sounds, or tastes can be a linking verb.
There are a few other verbs that behave like linking verbs in a particular context, in addition to: be, become, and seem.
