An idiom is a phrase with a figurative meaning that cannot be understood by translating its individual words literally.

Natural expression: Using phrases like break the ice or hit the nail on the head helps you sound more fluent and natural like a native speaker.

Cultural color: They add humor, emotion, and vivid imagery to daily conversation and writing.

Context is key: Because their real meaning is locked into the whole phrase rather than the sum of its parts, they must be learned as complete units rather than word-for-word
