An idiom (also called idiomatic expression) is an expression, word, or phrase that has a figurative meaning which is conventionally understood by native speakers. This meaning is different from the literal meaning of the idiom’s individual elements. In other words, idioms don’t mean exactly what the words say. They have, however, hidden meaning.
For your IELTS Speaking test, idiomatic language can be important because it is one of the elements in this component of the test the examiner looks for.
