1. Introduction — What Are Linking Verbs?

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.

2. Quick Summary

💡
A quick test If you can replace the verb with a form of "be" and the sentence still roughly makes sense, it's probably a linking verb: "She seems tired" → "She IS tired." This test doesn't work for action verbs: "She runs fast" → "She IS fast" changes the meaning, confirming "runs" here is an action verb, not linking.

4. Linking Verbs vs Action Verbs

Several common verbs (look, feel, taste, smell) can function as EITHER linking verbs or action verbs depending on meaning, and the grammar changes accordingly.

SentenceFunctionWhy
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.

5. The Classic Test Case — Good vs Well

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.

SentenceCorrect WordWhy
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.

6. Common Mistakes

❌ Incorrect✅ CorrectWhy
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.
