Unlocking the Meaning of Common English Idioms

Idioms are expressions whose meaning is different from the literal meaning of the words. They can be challenging for learners, because you can't always guess the meaning, but learning common idioms helps you understand native speakers and sound more natural.

Common idioms and their meanings

Break a leg: good luck (especially before a performance).
"Break a leg at your audition tomorrow!"

Hit the nail on the head: to say something exactly right.
"You hit the nail on the head when you said the meeting was too long."

Cost an arm and a leg: to be very expensive.
"I'd love that designer bag, but it costs an arm and a leg."

Let the cat out of the bag: to reveal a secret by accident.
"I accidentally let the cat out of the bag about the surprise party."

A piece of cake: very easy.
"The test was a piece of cake."

Get cold feet: to become nervous and think about not doing something.

In the same boat: in the same difficult situation as someone else.

Using idioms correctly

Idioms have fixed forms and meanings, so be careful. For example, break a leg is something you say to other people to wish them luck. If you say "I hope I don't break a leg", people will think you are worried about a real injury!

• Learn idioms in example sentences, not as single phrases.
