Those words are all linking verbs. They connect the subject of a sentence to a word that describes or identifies the subject.
Here's a breakdown:
* Linking verbs show a state of being or a condition. They don't show an action.
* Action verbs describe an action being done by the subject.
Examples:
* Linking verbs:
* The flowers smell beautiful. (The word "beautiful" describes the flowers.)
* She feels happy. (The word "happy" describes her state of being.)
* The cake tastes delicious. (The word "delicious" describes the cake.)
* Action verbs:
* The cat jumped onto the table. (The cat is performing an action.)
* They played in the park. (They are performing an action.)
