What is the effect of using an idiom in communication?

Using an idiom in communication serves to create clarity and relatability by allowing the speaker to convey ideas in a way that resonates with the audience's shared experiences or cultural references. Idioms can encapsulate complex ideas into familiar phrases, making them more accessible and easier to understand. When listeners recognize the idioms, they can relate to the ideas being expressed, enhancing their engagement and comprehension.

For instance, saying "it's raining cats and dogs" to describe heavy rain evokes a vivid image from everyday life, which draws on the listener's understanding of the idiom rather than requiring a literal interpretation. This familiarity fosters a stronger connection between the speaker and the audience, ultimately leading to more effective communication.
