Linking verbs serve as the quiet connective tissue of our sentences, quietly binding the subject to the rest of the clause without introducing any action. Unlike dynamic verbs that depict physical or mental activity, these verbs function as a bridge, equating the subject with a noun or adjective found after the verb. They do not describe what the subject is doing; instead, they describe what the subject is or how the subject appears, feels, or exists in a specific state.
Understanding the Core Function
The primary role of a linking verb is to connect the subject of a sentence to a subject complement. This complement provides essential information about the subject, either renaming it or describing its characteristics. To identify these verbs in a sentence, one can often substitute the verb with a version of "to be" without changing the fundamental meaning of the sentence. If the sentence remains logical, the verb in question is likely functioning as a linker, establishing a state of being rather than an action.
Common Linking Verbs
While action verbs like "run," "jump," or "think" imply activity, the following words typically function as links:
Forms of "to be" (am, is, are, was, were, been, being)
Sensory verbs such as "appear," "feel," "look," "sound," and "taste"
Verbs denoting a state of existence like "become," "seem," "remain," and "stay"
For example, in the sentence "The roses smell sweet," the verb "smell" links the subject "roses" to the adjective "sweet." Conversely, in "I smell the roses," the verb "smell" is an action verb because it describes the act of perceiving an odor.
Differentiating Action from Linking
A crucial skill in English grammar is distinguishing these verbs from action verbs. The test of substitution is the most reliable method. Consider the sentence "The soup tastes hot." If you replace "tastes" with "is"—"The soup is hot"—the sentence retains its logical meaning, confirming "tastes" is acting as a linker. However, in the sentence "She tastes the soup," replacing the verb with "is" results in nonsense ("She is the soup"), proving it is an action verb describing the act of using the tongue to perceive flavor.
The Role in Sentence Structure
Sentences utilizing these verbs follow a specific structure known as the Subject-Verb-Complement (SVC) pattern. The complement that follows the linker is vital; it modifies the subject and is necessary to complete the meaning. Without the complement, the statement feels incomplete. For instance, "The sky is" leaves the listener waiting for the description, whereas "The sky is blue" provides the full picture by identifying the specific state or quality of the subject.
Predicate Adjectives and Predicate Nouns
The words that follow a linking verb and describe the subject are called subject complements. If the complement is an adjective, it is known as a predicate adjective, describing a quality of the subject. If the complement is a noun or pronoun, it is a predicate noun, which renames the subject. In the sentence "He became a teacher ," "teacher" is a predicate noun. In "She seems confident ," "confident" is a predicate adjective.
