Linking verbs are a specialized category of verbs that do not express a physical or mental action but instead serve as a bridge between the subject of a sentence and additional information about that subject. Common examples of linking verbs include am, is, are, seem, look, and become, which function to establish a relationship of identity or description. Understanding these verbs is essential for any English learner because they allow us to describe states of being, appearances, and sensory perceptions with precision. By mastering linking verbs, writers and speakers can effectively connect subjects to adjectives or nouns, creating clear and grammatically sound descriptions of the world around them.

Definition and Fundamental Concept
A linking verb, also known as a copula or copular verb, is a verb that connects the subject of a sentence to a complement. This complement provides more information about the subject, such as its identity, condition, or characteristics. Unlike action verbs like run or jump, linking verbs do not tell us what the subject is doing; rather, they tell us what the subject is.
The most common linking verb in the English language is the verb to be. However, many other verbs can function in this capacity depending on how they are used in a sentence. The primary role of a linking verb is to act like an equal sign (=) in a mathematical equation. For example, in the sentence “The sky is blue,” the word is links the subject “sky” with the adjective “blue,” effectively stating that Sky = Blue.
Linking verbs are foundational to English syntax because they facilitate the use of subject complements. Without them, we would struggle to express basic states of existence or sensory experiences. They are categorized as “stative” because they describe a state rather than a dynamic process. This distinction is vital for learners to grasp, as it affects how these verbs interact with adverbs and adjectives.
Structural Breakdown of Linking Verb Sentences
To understand how linking verbs function, we must look at the sentence patterns they create. The most frequent pattern is Subject + Linking Verb + Subject Complement. The subject complement can be either a noun (renaming the subject) or an adjective (describing the subject).
When the complement is a noun, it is called a predicate nominative. For instance, in “Sarah is a doctor,” “doctor” is the predicate nominative that renames Sarah. When the complement is an adjective, it is called a predicate adjective. In “The soup tastes salty,” “salty” is the predicate adjective describing the soup. This structural requirement is why we use adjectives rather than adverbs after linking verbs.
It is important to note that linking verbs cannot have a direct object. Action verbs take direct objects (e.g., “He kicked the ball”), but linking verbs simply complete the description of the subject. If you can replace the verb in a sentence with “is,” “am,” or “are” and the sentence still makes sense, you are likely dealing with a linking verb structure.
Types and Categories of Linking Verbs
Linking verbs generally fall into three main categories: verbs of being, verbs of the senses, and verbs of condition or becoming. Understanding these categories helps learners recognize when a verb is acting as a link rather than an action.
Verbs of Being (The “To Be” Family)
These are the most frequent linking verbs. They include all forms of to be, such as am, is, are, was, were, be, being, and been. They represent the purest form of a link, simply stating that a condition exists or an identity is true. These verbs are almost always linking verbs, though they can occasionally serve as auxiliary (helping) verbs in progressive tenses.
Sensory Linking Verbs
These verbs relate to the five senses: look, sound, smell, feel, and taste. They describe how the subject is perceived by others or by the speaker. For example, “The flowers smell sweet.” In this context, the flowers aren’t performing the action of smelling; instead, they possess the quality of being sweet-smelling.
Verbs of Condition and Change
This category includes verbs like become, seem, appear, grow, turn, stay, and remain. These verbs describe a state of existence or a transition from one state to another. “The leaves turned red” indicates a change in state, where turned links the subject leaves to the adjective red.
Sensory Linking Verbs and State of Being
Sensory verbs are unique because they can often function as both action verbs and linking verbs. This duality is a common source of confusion for English students. When a sensory verb is used as a linking verb, it is followed by an adjective. When used as an action verb, it is followed by an adverb or a direct object.
Consider the verb feel. In the sentence “I feel cold,” feel is a linking verb connecting the subject “I” to the state of being “cold.” However, in “I feel the fabric carefully,” feel is an action verb describing a physical touch, modified by the adverb “carefully.” The key is to determine if the verb is describing the subject’s state or the subject’s action.
The state of being verbs like seem and appear are almost exclusively linking verbs. They suggest a perception of reality. “He seems tired” suggests that the state of the subject is one of fatigue. These verbs are essential for expressing nuance and subjectivity in descriptions, allowing the speaker to indicate that something might not be a definitive fact but is an observation.
Extensive Examples and Tables
To truly master linking verbs, it is helpful to see them used in a variety of contexts. Below are several tables categorizing common linking verbs and their usage in sentences. These tables provide a clear reference for how different verbs function as bridges between subjects and complements.
Table 1: Common Forms of “To Be” as Linking Verbs
The following table illustrates the most basic linking verbs in various tenses and person forms. These are the foundation of English descriptive sentences.

Comprehensive Usage Rules and Nuances
Mastering linking verbs requires an understanding of several specific grammatical rules. The most significant rule is that linking verbs are followed by adjectives, not adverbs. This is because the word following the verb is describing the subject (a noun or pronoun), and adjectives are the part of speech responsible for modifying nouns. For example, we say “I feel bad” (adjective) rather than “I feel badly” (adverb) when describing an emotional or physical state.
Another important rule involves the use of predicate nominatives. When a linking verb is followed by a noun that renames the subject, that noun should technically be in the subjective case. In formal English, one would say, “It is I” rather than “It is me.” While modern spoken English often accepts “It is me,” understanding the formal rule is vital for academic and professional writing.
Linking verbs also interact with prepositional phrases. Sometimes, a linking verb connects a subject to a phrase that describes its location or state. In the sentence “The book is on the shelf,” the verb is links “book” to the prepositional phrase “on the shelf.” This phrase functions as a subject complement by providing information about the subject’s current state of existence.
Linking Verbs vs. Action Verbs
One of the biggest challenges for learners is distinguishing between a verb’s linking use and its action use. Many verbs can play both roles. To determine which is which, use the Substitution Test. Replace the verb with a form of “to be” (am, is, are). If the sentence still makes sense and retains a similar meaning, the original verb is a linking verb.
Consider the verb grow. In “The gardener grows tomatoes,” grows is an action verb because the gardener is performing a task. You cannot say “The gardener is tomatoes.” However, in “The child grows tall,” grows is a linking verb. Replacing it gives us “The child is tall,” which makes sense and describes the child’s state.
This distinction is crucial because it dictates the rest of the sentence structure. Action verbs can be modified by adverbs (e.g., “He smelled the rose deeply”), while linking verbs are followed by adjectives (e.g., “The rose smelled deep/rich”). Recognizing the function of the verb prevents common errors in word choice.
Table 4: Action vs. Linking Comparison
| Verb | Used as Action Verb | Used as Linking Verb |
|---|---|---|
| Smell | He smelled the soup. | The soup smelled good. |
| Taste | I tasted the cake. | The cake tasted sweet. |
| Feel | She felt the fabric. | The fabric felt soft. |
| Look | They looked at the map. | The map looked confusing. |
| Sound | The captain sounded the alarm. | The alarm sounded loud. |
| Grow | Farmers grow corn. | The corn grew tall. |
| Turn | He turned the key. | His face turned red. |
| Appear | The magician appeared on stage. | He appeared tired. |
| Stay | We stayed at a hotel. | The room stayed warm. |
| Prove | She proved the theory. | The theory proved true. |
Common Mistakes and How to Avoid Them
The most frequent error involving linking verbs is the misuse of adverbs. Because many students are taught that verbs are modified by adverbs, they instinctively add an “-ly” ending to the word following a linking verb. This results in sentences like “The flowers smell sweetly” or “I feel badly.” Remember: Linking verbs describe the subject, and subjects are nouns, so use adjectives.
Another common mistake is confusing “well” and “good.” “Good” is an adjective, while “well” is usually an adverb (except when referring to health). Therefore, “I feel good” refers to your emotional state or the quality of your being, while “I feel well” specifically refers to your health. Saying “The dinner smells well” is incorrect because “well” is an adverb; it should be “The dinner smells good.”
Misidentifying the subject complement is also a hurdle. Students sometimes try to place a direct object after a linking verb. For example, in “He became a hero,” “hero” is not something he is acting upon; it is what he is. Understanding this prevents confusion when diagramming sentences or studying advanced grammar like passive voice, which linking verbs do not have.
Table 5: Correct vs. Incorrect Usage
| Incorrect Sentence | Correct Sentence | Explanation |
|---|---|---|
| The soup tastes saltily. | The soup tastes salty. | Use adjective after linking verb. |
| She looks beautifully today. | She looks beautiful today. | Describes her state, not an action. |
| I feel badly about the news. | I feel bad about the news. | “Bad” describes the subject’s state. |
| The dog smells badly. | The dog smells bad. | Unless the dog has a poor sense of smell. |
| The music sounds loudly. | The music sounds loud. | Adjective needed for description. |
| He became successfully. | He became successful. | Linking verbs take adjectives. |
| The plan seems wisely. | The plan seems wise. | Describes the plan, not the “seeming.” |
| The water turned coldly. | The water turned cold. | Describes the state of the water. |
| It is me. | It is I. (Formal) | Subjective case for predicate nominatives. |
| The cake smells deliciously. | The cake smells delicious. | Adjective for sensory link. |
Advanced Topics: Gerunds and Infinitives
For advanced learners, linking verbs can also connect subjects to more complex structures like gerunds or infinitives. A gerund is a verb ending in “-ing” that acts as a noun. In the sentence “My favorite hobby is swimming,” the linking verb is connects the subject “hobby” to the gerund “swimming.” Here, “swimming” acts as the predicate nominative.
Similarly, infinitives (the “to” form of a verb) can follow linking verbs. “His goal is to win” uses the linking verb is to connect “goal” with the infinitive “to win.” This structure is common when defining purposes, goals, or instructions. It allows for a high level of abstraction in English writing.
Furthermore, linking verbs can be used in the subjunctive mood, which expresses wishes, suggestions, or hypothetical situations. In the sentence “I suggest that he be prompt,” the verb be is a linking verb in the subjunctive form. Understanding these advanced applications allows students to navigate complex literature and formal academic discourse with confidence.

Frequently Asked Questions (FAQ)
1. Can a linking verb also be a helping verb?
Yes. Forms of the verb to be frequently act as helping (auxiliary) verbs in progressive tenses, such as “He is running.” In this case, is is helping the main action verb running. It is only a linking verb when it is the main verb connecting a subject to a complement.
2. Why can’t I use “badly” with “feel”?
In standard English, “feel” is a linking verb when describing an emotion or physical state. Linking verbs require adjectives. “Badly” is an adverb. If you say “I feel badly,” it technically means your sense of touch is impaired, as if your fingers are numb.
3. How do I tell if “look” is a linking verb or an action verb?
Use the replacement test. If you can replace look with is/are and it makes sense, it’s a linking verb. “She looks happy” -> “She is happy” (Correct, linking). “She looks at the tree” -> “She is at the tree” (Changes meaning significantly, action).
4. Are linking verbs the same as intransitive verbs?
Linking verbs are a type of intransitive verb because they do not take a direct object. However, not all intransitive verbs are linking verbs. For example, “He laughed” is intransitive but expresses an action, not a link to a description.
5. Is “become” always a linking verb?
Yes, become is almost exclusively used as a linking verb because its entire purpose is to show a change in the state or identity of the subject.
6. What is a predicate nominative?
A predicate nominative is a noun or pronoun that follows a linking verb and renames the subject. In “My father is a pilot,” “pilot” is the predicate nominative.
7. Can linking verbs be used in the passive voice?
No. Linking verbs cannot be passive because they do not have a direct object to move to the subject position. They describe a state of being, which is inherently active or static.
8. Do linking verbs have a tense?
Yes, linking verbs can be used in any tense: past (was), present (is), future (will be), present perfect (has been), etc. The tense indicates when the state of being existed.
Conclusion and Final Tips
Mastering linking verbs is a vital step toward achieving fluency and grammatical accuracy in English. These verbs serve as the essential glue that binds subjects to their descriptions, allowing us to communicate identity, sensory perception, and states of change. To ensure you use them correctly, always remember the distinction between actions and states, and lean on the substitution test when in doubt. Practice identifying these verbs in your daily reading, and pay close attention to whether they are followed by an adjective or a noun. By avoiding the common trap of using adverbs with linking verbs, you will significantly improve the clarity and professionalism of your writing. Keep practicing, and soon these structures will become a natural part of your linguistic repertoire.
