A-Z of English Idioms: 150 Most Common Expressions (2023)

Quick intro

An idiom is a phrase or group of words that, when taken together, has a meaning that is different from that of each individual word. To put it another way: idioms cannot be understood literally.

For example, ‘Once in a blue moon’ means ‘when something happens rarely’. So the example sentence: ‘I eat McDonalds once in a blue moon’ doesn’t make any sense when the words are taken literally (you only eat McDonalds when there is a blue moon?!). But when you understand the meaning of the idiom, the sentence makes perfect sense (you don’t often eat McDonalds).

Idioms are very important when learning English because they are used a lot in everyday communication and can help you sound more like a native. To speak and understand conversational English better, learning the correct use of idioms is essential. Idioms also help give character to the language; making it more colourful and interesting.

In this study guide, we’re going to walk you through the most common 150 English idioms used today, with their meanings and example sentences. We will also highlight a few outdated idioms that you should avoid, and give you some exercises to practise your understanding.
