Linking verbs connect the subject of a sentence to a noun, pronoun, or adjective that renames or describes the subject. They don't show action; instead, they link the subject to more information about it.
Here are some examples of linking verbs:
* be verbs: am, is, are, was, were, been, being
* sense verbs: feel, smell, taste, look, sound
* other linking verbs: appear, become, seem, grow, remain, stay, turn
Examples:
* The sky is blue. (The linking verb "is" connects the subject "sky" to the adjective "blue" that describes it.)
* She feels happy. (The linking verb "feels" connects the subject "she" to the adjective "happy" that describes her.)
* The cake smells delicious. (The linking verb "smells" connects the subject "cake" to the adjective "delicious" that describes it.)
In contrast to action verbs, which describe an action, linking verbs provide information about the state or condition of the subject.
