An idiom is a group of words or a phrase with a meaning that is not deducible from the individual words’ definitions.
Idioms often have cultural or regional significance and are used in language to express ideas, emotions, or concepts in a figurative or metaphorical way.
Common examples include “kick the bucket” (meaning to die), “hit the nail on the head” (meaning to be exactly right), and “barking up the wrong tree” (meaning pursuing a mistaken or unproductive course of action).
Idioms add richness and depth to language and can be challenging for non-native speakers to understand.
