which statement best describes a defining feature of a compound adjective

Answer 1

A compound adjective is a descriptive term that is formed by combining two or more words to create a single adjective that modifies a noun. The defining feature of a compound adjective is that it often uses hyphens to link the words together when they appear before the noun they modify (e.g., "well-known author," "high-speed train"). This hyphenation helps clarify that the words function together as one descriptive unit.
