Here are 10 English idioms that don’t make much sense at first, but are super fun once you learn them.

1. Spill the Beans

Meaning: To reveal a secret.
Example: Don’t spill the beans about the surprise party!

💡 Origin: Possibly from ancient Greece, where people used beans to vote secretly. Spilling them would reveal the result early.

2. It’s Raining Cats and Dogs

Meaning: It’s raining very heavily.
Example: We can’t go outside—it's raining cats and dogs!

💡 No one really knows where this came from, but one guess is that in old England, heavy rain would wash dead animals through the streets. (Gross, but memorable!)

3. Break the Ice

Meaning: To start a conversation in a social setting.
Example: Telling a joke is a great way to break the ice at a party.

💡 Imagine ships breaking ice to start moving—same idea for conversations!

4. Let the Cat Out of the Bag

Meaning: To reveal a secret by accident.
Example: He let the cat out of the bag about her promotion.

💡 This might come from old markets where people sold pigs in bags—but sometimes cheated and put cats inside instead!

6. Kick the Bucket

7. Hit the Nail on the Head

💡 Old sailors said this when they felt seasick during storms.

9. Cost an Arm and a Leg

Meaning: Something very expensive.
Example: That designer bag cost an arm and a leg!

💡 Some believe it comes from war injuries; others say it’s from portrait artists charging more for including limbs!

10. The Ball is in Your Court

💡 This comes from tennis—once the ball is on your side, it’s your move.
