An idiom is a phrase or expression that typically presents a figurative, non-literal meaning attached to the phrase. It is a type of formulaic language that cannot be understood simply by looking at the meaning of the individual words in the phrase. Idioms are essentially the verbal equivalent of using the wrong math formula but still getting the correct answer. They are peculiar to a language and are used to convey a message in a more creative way. Idioms are not easily translatable and are assimilated into a languages vocabulary. They are a feature of modern language and are used in both spoken and written communication. Idioms are an important aspect of language learning, and understanding them is crucial for effective communication.
