Idioms are phrases whose meaning cannot be predicted from the individual words. "Break a leg" does not mean to fracture a bone — it means good luck. Knowing common idioms makes your English sound natural and helps you understand native speakers who use them constantly.
Idioms for daily life. "It's raining cats and dogs" means raining heavily. "Break a leg" means good luck. "Hit the nail on the head" means to be exactly right. "Let the cat out of the bag" means to reveal a secret. "Cost an arm and a leg" means very expensive.
Idioms for feelings. "I'm feeling under the weather" means feeling sick. "On cloud nine" means extremely happy. "Feeling blue" means feeling sad. "Butterflies in my stomach" means nervous. "Keep your chin up" means stay positive during difficulty.
Idioms for work and success. "Burn the midnight oil" means to work late at night. "The ball is in your court" means it is your turn to make a decision. "Get the ball rolling" means to start something. "A piece of cake" means very easy. "Bite off more than you can chew" means to take on too much.
Idioms for communication. "Beat around the bush" means to avoid the main topic. "Get to the point" means to say what matters directly. "Actions speak louder than words" means behavior reveals true intentions. "The ball is in your court" means the decision is now yours.
When NOT to use idioms. In formal writing — IELTS essays, academic papers, professional emails — idioms are usually inappropriate. Use them in casual conversation, storytelling and informal communication. Knowing when to use them is just as important as knowing what they mean.
How to learn idioms naturally. Watch English TV shows and note idioms in context. Ask yourself: what does this phrase mean based on the situation? Write down three new idioms each week and try to use at least one in a conversation. Shaista introduces one new idiom per class at LEWS Academy, and students practice using them in role-play scenarios.
