Which statement best defines a verb?

• A. A word that expresses an action or a state of being.
• B. A word that describes a noun.
• C. A word that modifies a noun.
• D. A word that connects words.

Answer: (A)

Verbs are the words that express action or state of being. They tell what someone or something does, like run, eat, think, or feel, and they can also describe a state such as exist or belong. Verbs carry information about time through tense (walk, walks, walked, will walk) and link the action or state to the subject of the sentence, forming the core of the predicate. The other options describe other parts of speech: describing a noun is what adjectives do, changing details about a noun is also an adjective or determiner, and linking words together is the job of conjunctions or connecting words. So the best definition is a word that expresses an action or a state of being.
