Everything you need to understand linking verbs in English, why they take adjectives not adverbs, and how to tell them apart from action verbs, with exam practice.
Linking verbs (also called copular verbs) connect the subject of a sentence to a description of it, rather than showing an action. "She seems tired" doesn't describe something Sarah does, it describes a quality of Sarah herself. This matters grammatically because linking verbs are followed by an adjective, not an adverb, the exact opposite of what many learners instinctively reach for.
| Linking Verb | Example |
|---|---|
| be | She is intelligent. |
| seem | He seems nervous. |
| become | It became clear that we were lost. |
| appear | The situation appears complicated. |
| feel | I feel tired today. |
| look | You look happy. |
| sound | That sounds great. |
| taste | This soup tastes delicious. |
| smell | The bread smells amazing. |
| get (informal, become) | It's getting late. |
| remain | The room remained silent. |
| turn | The leaves turn brown in autumn. |
Several common verbs (look, feel, taste, smell) can function as EITHER linking verbs or action verbs depending on meaning, and the grammar changes accordingly.
| Sentence | Function | Why |
|---|---|---|
| She looks happy. | Linking (+ adjective) | Describes her appearance/state. |
| She looked at the photo carefully. | Action (+ adverb) | Describes how she performed the action of looking. |
| The soup tastes good. | Linking (+ adjective) | Describes a quality of the soup. |
| He tasted the soup carefully. | Action (+ adverb) | Describes how he performed the action of tasting. |
The most commonly tested linking-verb pattern involves "good" (adjective) and "well" (usually an adverb). After a linking verb, "good" is correct; after an action verb, "well" is correct.
| Sentence | Correct Word | Why |
|---|---|---|
| The food tastes ___. | good | "Taste" here is linking; needs an adjective. |
| She sings ___. | well | "Sing" here is an action; needs an adverb. |
| I feel ___ today. | good | "Feel" here is linking (describing a state); needs an adjective. |
For the complete rule, including the special case where "well" itself is also an adjective (meaning "healthy"), see our full guide to Good vs Well.
| ❌ Incorrect | ✅ Correct | Why |
|---|---|---|
| She looks beautifully. | She looks beautiful. | "Looks" here is linking (describing her appearance), so it needs an adjective, not an adverb. |
| This cake tastes deliciously. | This cake tastes delicious. | "Tastes" is linking here; the adverb form is incorrect after it. |
| I feel badly about it. | I feel bad about it. | "Feel" describing an emotional state is linking and needs the adjective "bad," not the adverb "badly." |
| He became successfully. | He became successful. | "Become" is always a linking verb and always needs an adjective. |
| Exam | How This Is Tested | Sample Question |
|---|---|---|
| Cambridge B1 Preliminary / B2 First | The adjective-after-linking-verb rule is a classic Use of English error-correction pattern. | "She looked beautifully at the party." → identify and correct the error. |
| IELTS Speaking | Accurate use of linking verbs with adjectives (not adverbs) is a basic accuracy marker across all bands. | "The experience sounds amazing" used naturally when describing something. |
| Trinity GESE/ISE (SELT) | Describing feelings and reactions naturally relies heavily on linking verbs. | "I feel nervous about the interview." |
