Definition of an Idiom

An idiom is a phrase or expression whose meaning cannot be deduced from the literal definition of the words. These phrases often have a cultural or historical context and are used to convey a specific idea or emotion. Idioms are used in everyday conversation and can add color and depth to the language.

Examples of common idioms include “break a leg,” which means good luck, and “cost an arm and a leg,” which means something is very expensive.

Origin and Meaning of “Catch Me Out”

The phrase “catch me out” has its roots in British English and was first recorded in the 1880s. The term “catch” is often used in English to mean “to discover” or “to expose,” and “me out” is a way of saying “me in the act of doing something wrong.”
