(A) Phrase
(B) Idiom
(C) Adjective
(D) None of these
🧠 Explanation:
An idiom is a fixed expression whose meaning cannot be understood by interpreting the individual words. It conveys a culturally accepted idea, often figurative rather than literal. Grammatically, idioms usually function as noun phrases or clauses, depending on their structure. The phrase “fixed meaning” here is key, as idioms retain their meaning regardless of word changes. For example, “spill the beans” means to reveal a secret, not literally dropping beans. Alternatives like “expression” or “phrase” exist, but they may not always carry the same figurative sense. Idioms make language more colorful and help convey ideas vividly and memorably.
