What is an example of a verb?

The correct choice is "Run" because it is a verb, which is defined as a word that represents an action, occurrence, or state of being. In this case, "run" describes the action of moving swiftly on foot.

Other options include nouns and adjectives. "Happiness" is a noun that refers to a state of well-being or joy. "Quickly" is an adverb that modifies verbs, adjectives, or other adverbs by indicating the manner of an action. "Beautiful" is an adjective used to describe a quality, typically of a noun. Understanding these distinctions is crucial in identifying parts of speech accurately in business writing and document production.
