Chapter 2

Having discussed what idioms are in Chapter 1 and how they compare with other forms of figurative speech such as metaphors and similes, this second chapter on the topic next focuses on their use in general contexts. If you’re studying English at an advanced level and wish to sound more like a native speaker, then learning a handful of high-frequency idiomatic phrases such as ‘raining cats and dogs’ or ‘hit the spot’ is a good step in the right direction. We provide just under a hundred of the most common idioms below with examples and definitions to help inform their use.

What are the key points about idioms?

As a quick review of Chapter 1, remember that idioms are:

  • common in English, with over 25,000 possibilities
  • phrases of two or more words which when combined create new meanings
  • figurative expressions which attach a non-literal meaning to an otherwise literal phrase
  • different to other types of figurative language like metaphors (“man of steel”), similes (“brave as a lion”), hyperbole (“I’ve told you a million times”) and proverbs (“haste makes waste”)


Are idioms more common in speech or writing?

While idioms can certainly be found in the written form, it’s important to remember (particularly if you’re studying English for academic purposes: EAP) that most genres of writing are formal in nature and that idioms are quite informal. You may see idioms when messaging on social networks for example, or on blogs or in novels, but you would rarely see them in advanced textbooks or journal articles and would rarely use them when writing essays. In speech, however, idioms are quite common, and may be used by a native speaker as a more creative and playful form of expression.
