How this list is arranged
The idioms are grouped by theme. The themes are work, money, weather, feelings, food and animals, and time. A theme is a place to start, not a rule.
“Burn the midnight oil” sits with work because its meaning is working late, which is usually a job or a study task. It is also about time.
A theme shows as a button only when the list has an idiom for it, so some themes fill up as more idioms are added. Use a button to show one group, or type a word in the box to find a phrase by its meaning.
Every idiom page follows the same plan, so you can find each part quickly. First comes one sentence that says what the phrase means. Then come two examples that you can listen to and a quick check of three questions.
After that you will find notes on how the phrase sounds in Australia, the UK and the US. Further down you will find what the words say and what the phrase really means, common mistakes, and other ways to say the same thing.
All the wording on these pages is written by EasySay in plain English. It is not copied from a dictionary or from another website.
Notes about who can say what, and in which country, are a judgement, so a person reads each one before a page is released. If you think a note is wrong, use the Report a mistake link at the bottom of the page.
The quiz near the top asks ten questions, and each one is about a different idiom from this list. Answer one at a time and read the short reason after each check.
The Quick check keeps no score and has no timer. If a question is hard, open that idiom’s page and try its own three questions.
Questions people ask
What is an idiom?
An idiom is a short phrase whose meaning is not clear from its separate words. “Bite the bullet” means to face something hard. It has nothing to do with a real bullet.
Can I use idioms at work?
Often yes. Friendly idioms such as “under the weather” are common with colleagues. In a formal letter or with a customer, plain words are usually safer. Each page says how its idiom sounds.
Do idioms mean the same in every country?
Many do, but not all. Some idioms are used more in one country, and a few change a word, such as “beat around the bush” and “beat about the bush”. Each page has notes for Australia, the UK and the US.
How should I practise idioms?
Read the plain meaning, say the two examples aloud, then answer the quick check. Try to use one new idiom in a message to a friend this week.
