Which word is an adverb?

An adverb describes how an action is performed, often modifying a verb. Here, rapid is an adjective meaning fast, while rapidly is the adverb form created by adding -ly. Rapidly answers how something is done, as in “The runner moved rapidly.” The other forms are nouns or adjectives (rapid describes a noun, rapidness and rapidity are nouns), so they don’t function as adverbs.
