What is an idiom?

An idiom is a group of words whose meaning is different from the meanings of the individual words. It's raining cats and dogs has nothing to do with animals; it means that it is raining very heavily. Break the ice does not involve ice; it means making people feel comfortable when they first meet.

Because they cannot be understood word by word, idioms are one of the last hurdles for advanced learners, and one of the first things that make speech sound natural. They are especially common in conversation, fiction and journalism.

How to use idioms naturally

  • Learn them in a sentence. An idiom alone is easy to misuse; the example shows its tone and grammar.
  • Check the register. Most idioms are informal. Hit the books is fine with friends, less so in an essay.
  • Don't change the words. Idioms are fixed: it is a piece of cake, not a slice of cake.
  • Use them sparingly. One well-placed idiom sounds natural; five in a paragraph sounds like a textbook.
  • Watch the verb. Many idioms start with a verb that changes form: bite the bullet → I bit the bullet.

How to learn idioms

  1. Start with the very common group: you will hear these in films and conversations every week.
  2. Learn a few at a time, with their example sentences, and try to use one in your own sentence.
  3. Test yourself with the quiz above; the wrong options are other idioms' meanings, so it trains recognition.
  4. Read stories. Idioms are learned best when you meet them in context. In the Okuzeka reader, tapping an idiom in a book explains what the whole expression means in that sentence.
