Final answer:
The word 'happy' is an adjective and not an action verb.
Step-by-step explanation:
The word 'happy' is NOT an action verb. Action verbs are words that describe an action or a process. For example, 'trained,' 'tested,' and 'designed' are all action verbs because they describe specific actions. However, 'happy' is an adjective that describes a state of being or a feeling, not an action. Adjectives describe nouns or pronouns, but they do not show any action.
