Definition of Linking Verbs
A linking verb, also known as a copula, is a verb that connects the subject of a sentence to a noun or adjective that describes or renames the subject. Unlike action verbs, linking verbs do not express an action performed by the subject. Instead, they establish a relationship between the subject and its complement (the word or phrase that follows the linking verb and provides information about the subject). The primary function of a linking verb is to equate the subject with its complement or to indicate a state of being.
Classification and Function
Linking verbs can be classified into several categories, including forms of the verb “to be” (am, is, are, was, were, be, being, been), verbs of sensation (look, smell, taste, sound, feel), and verbs that indicate a state of being or becoming (seem, appear, become, grow, turn, remain, stay). Each type of linking verb serves the same fundamental purpose: to connect the subject to a subject complement. The subject complement can be a noun, pronoun, or adjective that provides additional information about the subject.
Contexts of Use
Linking verbs are used in a variety of contexts to describe characteristics, conditions, and identities. They are frequently used in descriptive writing to provide details about the subject’s appearance, qualities, or state of mind. In formal writing, linking verbs are often used to present definitions, classifications, or explanations. In everyday conversation, linking verbs are used to express opinions, observations, and personal feelings. Understanding the various contexts in which linking verbs are used can help you to use them more effectively and appropriately.
Structural Breakdown
The basic structure of a sentence with a linking verb is Subject + Linking Verb + Subject Complement. The subject is the noun or pronoun that the sentence is about. The linking verb connects the subject to the subject complement, which provides additional information about the subject. The subject complement can be a predicate nominative (a noun or pronoun that renames the subject) or a predicate adjective (an adjective that describes the subject).
Subject + Linking Verb + Predicate Nominative
In this structure, the subject complement is a noun or pronoun that renames the subject. The subject and the predicate nominative refer to the same person, place, or thing. For example, in the sentence “John is a doctor,” “John” is the subject, “is” is the linking verb, and “a doctor” is the predicate nominative. “A doctor” renames “John,” indicating his profession.
Subject + Linking Verb + Predicate Adjective
In this structure, the subject complement is an adjective that describes the subject. The adjective provides information about the subject’s qualities or characteristics. For example, in the sentence “The sky is blue,” “The sky” is the subject, “is” is the linking verb, and “blue” is the predicate adjective. “Blue” describes the color of the sky.
Identifying Linking Verbs
One way to identify linking verbs is to determine whether the verb connects the subject to a word or phrase that describes or renames it. If you can replace the verb with a form of “to be” (e.g., is, are, was, were) and the sentence still makes sense, it is likely a linking verb. For example, in the sentence “The soup tastes delicious,” you can replace “tastes” with “is” to form “The soup is delicious,” which is grammatically correct and retains the original meaning. This indicates that “tastes” is a linking verb in this context.
Types and Categories of Linking Verbs
Linking verbs can be categorized into several types based on their function and meaning. The most common categories include forms of “to be,” verbs of sensation, and verbs of state of being or becoming.
Forms of “To Be”
The forms of “to be” (am, is, are, was, were, be, being, been) are the most common linking verbs. They are used to express a state of being or to connect the subject to a predicate nominative or predicate adjective. These verbs are versatile and can be used in a wide range of contexts to describe conditions, identities, and characteristics. For example, “I am a student,” “They are happy,” and “The book was interesting” all use forms of “to be” as linking verbs.
Verbs of Sensation
Verbs of sensation (look, smell, taste, sound, feel) can function as linking verbs when they describe the qualities perceived by the senses. In these cases, the verb connects the subject to an adjective that describes the sensory experience. For example, “The flower smells sweet,” “The music sounds beautiful,” and “The fabric feels soft” all use verbs of sensation as linking verbs.
Verbs of State of Being or Becoming
Verbs of state of being or becoming (seem, appear, become, grow, turn, remain, stay) indicate a change in state or condition. These verbs connect the subject to a predicate nominative or predicate adjective that describes the resulting state. For example, “He seems tired,” “She became a teacher,” and “The milk turned sour” all use verbs of state of being or becoming as linking verbs.
Examples of Linking Verbs
The following tables provide extensive examples of linking verbs in various contexts, categorized by type.
Examples with Forms of “To Be”

Usage Rules for Linking Verbs
Using linking verbs correctly involves understanding their function and following specific grammatical rules. Here are some key rules to keep in mind.
Subject-Verb Agreement
Linking verbs must agree in number with their subjects. Singular subjects require singular verbs, while plural subjects require plural verbs. For example, “He is a student” (singular) and “They are students” (plural).
Predicate Nominatives and Predicate Adjectives
The subject complement must agree in number with the subject when it is a predicate nominative. For example, “My favorite fruit is apples” (plural) and “My favorite fruit is an apple” (singular). Predicate adjectives do not need to agree in number with the subject, as adjectives do not change form to indicate number.
Adjectives vs. Adverbs
When using verbs of sensation as linking verbs, use adjectives to describe the subject. Avoid using adverbs, as adverbs modify verbs, not subjects. For example, “The flower smells sweet” (correct) vs. “The flower smells sweetly” (incorrect). The adjective “sweet” describes the flower, while the adverb “sweetly” would describe how the flower smells (an action).
Exceptions and Special Cases
Some verbs can function as both linking verbs and action verbs, depending on the context. For example, “look” can be a linking verb (e.g., “She looks tired”) or an action verb (e.g., “She looked at the painting”). To determine whether a verb is functioning as a linking verb, try replacing it with a form of “to be.” If the sentence still makes sense, it is likely a linking verb.
Common Mistakes with Linking Verbs
Several common mistakes can occur when using linking verbs. Being aware of these errors can help you to avoid them in your own writing.
Using Adverbs Instead of Adjectives
One of the most common mistakes is using adverbs instead of adjectives after verbs of sensation. Remember to use adjectives to describe the subject, not adverbs to describe the verb.
| Incorrect | Correct | Explanation |
|---|---|---|
| The soup tastes badly. | The soup tastes bad. | “Badly” is an adverb, while “bad” is an adjective that describes the soup. |
| The music sounds loudly. | The music sounds loud. | “Loudly” is an adverb, while “loud” is an adjective that describes the music. |
| He looks sadly. | He looks sad. | “Sadly” is an adverb, while “sad” is an adjective that describes his appearance. |
Subject-Verb Agreement Errors
Another common mistake is failing to ensure subject-verb agreement. Make sure that the linking verb agrees in number with the subject.
| Incorrect | Correct | Explanation |
|---|---|---|
| They is happy. | They are happy. | “They” is a plural subject, so it requires the plural verb “are.” |
| He were a student. | He was a student. | “He” is a singular subject, so it requires the singular verb “was.” |
| The flowers is beautiful. | The flowers are beautiful. | “The flowers” is a plural subject, so it requires the plural verb “are.” |
Misidentifying Linking Verbs
Sometimes, verbs that can be linking verbs are used as action verbs. It’s important to correctly identify when a verb is linking the subject to a description or renaming of the subject, rather than showing an action.
| Incorrect (Action Verb) | Correct (Linking Verb) | Explanation |
|---|---|---|
| He looked the answer. | He looks tired. | In the first sentence, “looked” is an action verb, meaning he searched for the answer. In the second sentence, “looks” is a linking verb, describing his appearance. |
| She tasted the soup carefully. | The soup tastes delicious. | In the first sentence, “tasted” is an action verb, meaning she actively tasted the soup. In the second sentence, “tastes” is a linking verb, describing the soup’s flavor. |

Advanced Topics
For advanced learners, understanding the nuances of linking verbs in complex sentence structures and idiomatic expressions can further enhance their grammar skills.
Linking Verbs in Complex Sentences
In complex sentences, linking verbs can appear in subordinate clauses, connecting the subject of the clause to its complement. For example, in the sentence “I think that he is a good person,” “is” is a linking verb in the subordinate clause “that he is a good person.” Recognizing linking verbs in complex sentences is essential for understanding the grammatical structure and meaning of the entire sentence.
Linking Verbs in Idiomatic Expressions
Linking verbs are often used in idiomatic expressions, where the meaning of the expression is different from the literal meaning of the words. For example, “to be in the dark” means to be unaware or uninformed. Understanding the idiomatic uses of linking verbs can improve your comprehension and fluency in English.
Distinguishing Linking Verbs from Auxiliary Verbs
It is important to distinguish linking verbs from auxiliary verbs, which are used to form different tenses and moods of verbs. Auxiliary verbs do not connect the subject to a subject complement; instead, they help to express the action or state of being in a specific tense or mood. For example, in the sentence “I am studying,” “am” is an auxiliary verb that helps to form the present continuous tense of the verb “study.”
Frequently Asked Questions (FAQ)
Here are some frequently asked questions about linking verbs.
- What is the difference between a linking verb and an action verb?
A linking verb connects the subject of a sentence to a noun or adjective that describes or renames the subject, while an action verb expresses an action performed by the subject. Linking verbs do not express action; they establish a relationship or state of being. For example, “She is a doctor” (linking verb) vs. “She runs quickly” (action verb).
- How can I identify a linking verb in a sentence?
To identify a linking verb, determine whether the verb connects the subject to a word or phrase that describes or renames it. If you can replace the verb with a form of “to be” (e.g., is, are, was, were) and the sentence still makes sense, it is likely a linking verb. For example, in “The coffee smells strong,” replacing “smells” with “is” gives “The coffee is strong,” which is grammatically correct.
- What are the most common linking verbs?
The most common linking verbs are forms of “to be” (am, is, are, was, were, be, being, been), verbs of sensation (look, smell, taste, sound, feel), and verbs of state of being or becoming (seem, appear, become, grow, turn, remain, stay).
- Why is it important to use adjectives instead of adverbs after linking verbs?
Adjectives describe nouns or pronouns, while adverbs describe verbs, adjectives, or other adverbs. After a linking verb, you need an adjective to describe the subject of the sentence. Using an adverb would incorrectly modify the verb instead of describing the subject. For example, “The flower smells sweet” (adjective describing the flower) vs. “The flower smells sweetly” (incorrect, as “sweetly” would describe how the flower smells, not the flower itself).
- Can a verb be both a linking verb and an action verb?
Yes, some verbs can function as both linking verbs and action verbs, depending on the context. For example, “look” can be a linking verb (e.g., “She looks tired”) or an action verb (e.g., “She looked at the painting”).
- What is a predicate nominative?
A predicate nominative is a noun or pronoun that follows a linking verb and renames the subject of the sentence. The subject and the predicate nominative refer to the same person, place, or thing. For example, in the sentence “John is a doctor,” “a doctor” is the predicate nominative that renames “John.”
- What is a predicate adjective?
A predicate adjective is an adjective that follows a linking verb and describes the subject of the sentence. For example, in the sentence “The sky is blue,” “blue” is the predicate adjective that describes the sky.
- How do I ensure subject-verb agreement with linking verbs?
Ensure that the linking verb agrees in number with the subject. Singular subjects require singular verbs, while plural subjects require plural verbs. For example, “He is a student” (singular) and “They are students” (plural).
Conclusion
Mastering linking verbs is essential for constructing grammatically correct and meaningful sentences in English. By understanding the definition, types, usage rules, and common mistakes associated with linking verbs, you can improve your writing and speaking skills.
