Определение и Значение "compound adjective"

What is a "compound adjective"?

A compound adjective is an adjective that consists of two or more words combined to modify a noun. These adjectives often use hyphens to connect the words, creating a single descriptive unit. For example, in the phrase "well-known author," the compound adjective "well-known" describes the noun "author" and indicates that the author is famous. Another example is "high-speed train," where "high-speed" describes the noun "train" and indicates its capability. Compound adjectives enhance descriptions by providing more specific information about the nouns they modify, making them important for clearer communication in language.
