A verb tells us what someone or something does, or what state they are in. Every complete sentence needs a verb.
Action verbs
Action verbs describe things we can do: run, write, eat, jump, think.
The children play in the garden.
Linking verbs
Linking verbs do not show action. They connect the subject to a description: is, am, are, was, seem, become, feel.
The soup tastes delicious. She is happy.
Quick tip
Ask yourself: “What is happening?” or “What is the subject like?” The answer usually leads you to the verb.
