Which word is typically classified as an adjective?

The word "high" is typically classified as an adjective because it describes a quality or characteristic of a noun. Adjectives are words that modify nouns by providing more information about them, such as their appearance, size, quantity, or other attributes. In this case, "high" can be used to describe something that is elevated in position or stature, as in "the high building" or "the high mountain."

While "quick" and "blue" are also adjectives, the question asks for one specific example, and "high" is often recognized in contexts describing emotional or physical states, as well as spatial dimensions. The words "run" is a verb, indicating an action rather than a quality. Thus, the distinction in classification clearly supports "high" as an adjective, emphasizing its role in providing descriptive details about a noun.
