What is an IDIOM?

An idiom is a phrase that uses words you already know, but combines them in such a way that the phrase conveys another meaning. Like any spoken language, English is filled with idioms. Becoming familiar with idioms will help you understand, and eventually produce, native-sounding English. It is idiomatic language, a rich carrier of culture, that will give you the fluency of an English speaker.    Search Idioms >
