A compound adjective is formed by combining two or more words to describe a noun. These adjectives work together to convey a specific attribute or characteristic, often adding precision to descriptions.
Hyphens are typically used to connect the words, such as in “well-known,” “high-quality,” or “two-year-old.” Compound adjectives help provide more nuanced and detailed information about the noun they modify.
They can be composed of nouns, adverbs, or adjectives, and their unique combinations enable richer and more expressive language, enhancing the overall clarity and meaning of sentences.
