10 idioms that don’t make sense (but English people love them)

English is full of strange expressions that make no sense—unless you’re a native speaker. If you’ve ever heard someone say they’re “over the moon” or “under the weather” and thought, “Wait, what?”—you’re not alone.

These expressions are called idioms—phrases that don’t mean exactly what the words say. They can be funny, confusing, and even a little weird… but native speakers use them all the time.

Let’s take a look at 10 English idioms that make no sense (but people love them anyway)—and what they actually mean.

1. It’s raining cats and dogs

🐱🐶
Meaning: It’s raining very heavily.
Example: “Don’t forget your umbrella—it’s raining cats and dogs out there!”

🎯 No, animals are not falling from the sky. But this idiom is a classic.

2. Kick the bucket

👟🪣
Meaning: To die (informal or humorous)
Example: “He finally kicked the bucket at age 98.”

🎯 It sounds silly, but it’s a surprisingly common euphemism for death.

3. Let the cat out of the bag

🐈👜
Meaning: To reveal a secret
Example: “I was planning a surprise party, but Sarah let the cat out of the bag.”

🎯 Cats and bags? It’s an odd image, but the idea is: once the cat’s out, you can’t hide it again!

4. Break the ice

❄️🧊
Meaning: To start a conversation in a social situation
Example: “He told a joke to break the ice at the meeting.”

🎯 No ice needs to be broken—just silence and awkwardness.

5. Bite the bullet

😬🔫
Meaning: To do something difficult or unpleasant that you’ve been avoiding
Example: “I hate going to the dentist, but I finally bit the bullet and made an appointment.”

🎯 This phrase comes from old times when soldiers bit on a bullet during surgery—ouch.

6. Hit the sack

🛏️🥱
Meaning: To go to bed or go to sleep
Example: “I’m exhausted—I’m going to hit the sack.”

🎯 There’s no sack involved. Just sleep.

7. Cost an arm and a leg

💸🦵🦾
Meaning: Very expensive
Example: “That new phone cost me an arm and a leg.”

🎯 No body parts were lost—just a lot of money.

8. Under the weather

🌧️🤒
Meaning: Feeling ill or unwell
Example: “I’m feeling a bit under the weather today.”

🎯 The weather didn’t fall on them—they just have a cold.

9. Spill the beans

🥫😮
Meaning: To reveal a secret or spoil a surprise
Example: “Don’t spill the beans about the gift!”

🎯 Beans = secrets? Not logically, but it works.

10. The ball is in your court

🎾⏳
Meaning: It’s your turn to make a decision or take action
Example: “I sent him the contract—the ball’s in his court now.”

🎯 There’s no tennis match here. Just responsibility.

🧠 Why Are Idioms So Weird?

Idioms are part of the culture and history of a language. They often come from old stories, traditions, or professions (like war, farming, or sailing). Over time, their literal meanings were forgotten—but the phrases stayed.

They don’t follow grammar rules, and they can’t be translated word-for-word—which makes them difficult for learners.

✅ How to Learn Idioms (Without Going Crazy)

Learn them in context – see them used in real sentences
Don’t translate – learn the meaning directly in English
Use them naturally – don’t overuse them, especially in formal writing
Watch English TV or movies – idioms are everywhere in spoken English

🗣️ Final Thoughts

Idioms might not make sense literally, but they bring color, humor, and personality to the English language. If you can understand (and use) a few of them, you’ll sound more fluent and more natural.

So the next time someone “spills the beans” or says something “costs an arm and a leg,” you’ll know exactly what they mean—no dictionary required.
