Common English Idioms Explained

English, like all languages, is peppered with colourful idioms that, when taken literally, might leave one scratching their head. 

Idioms are unique phrases that carry a figurative meaning different from their literal interpretation. They enrich language, add depth to expression, and reflect cultural nuances. 

Here’s a deep dive into some popular English idioms and the intriguing stories behind them.

1. Bite the Bullet

Meaning: To face a difficult or unpleasant situation with courage.

Origin: In the old days, before anesthesia, injured soldiers would bite on a bullet to cope with the pain during surgery. The act symbolised enduring short-term pain for long-term relief.

2. The Ball is in Your Court

Meaning: It’s your move or decision now.

Origin: This phrase comes from the world of sports, notably tennis. When the ball is hit into your side of the court, it’s your turn to respond.

3. Break a Leg

Meaning: A way to wish someone good luck, especially before a performance.

Origin: The origins are debated, but one theory is that actors believed wishing someone “good luck” outright would jinx them. Instead, they chose an ironic phrase. Another theory suggests it refers to the act of taking a bow after a successful performance, where the leg bends or “breaks.”

4. Let the Cat Out of the Bag

Meaning: Reveal a secret.

Origin: In medieval times, merchants would often display piglets for sale in bags. Sometimes, an unscrupulous seller would replace the pig with a less valuable cat. If someone let the cat out, the deception was exposed.

5. Hit the Hay

Meaning: To go to bed.

Origin: Before the invention of mattresses, people would sleep on bags of hay. Thus, “hitting the hay” referred to lying down on one’s hay bed.

6. Jump on the Bandwagon

Meaning: Adopting a popular trend or activity.

Origin: In the 19th century, a bandwagon was a wagon carrying a circus band. Politicians saw the advantage of participating in these events to gain popularity, so they would “jump on” to associate themselves with something successful.

7. Costs an Arm and a Leg

Meaning: Very expensive.

Origin: Theories suggest this phrase originated post-WWII, referring to soldiers who lost limbs and paid a high price. Another theory posits it’s related to 18th-century portraits where painters charged more for larger paintings, including limbs.

8. Under the Weather

Meaning: Feeling ill.

Origin: This nautical phrase comes from ailing sailors who would go below deck to avoid bad weather and recover, hence being “under the weather.”

9. Don’t Throw the Baby Out with the Bathwater

Meaning: Be careful not to discard something valuable in your eagerness to get rid of some useless thing associated with it.

Origin: In the 1500s, the household shared bathwater, with the baby being the last to be bathed. The water would be so murky by then that one could lose something (even a baby) in it!

10. Kick the Bucket

Meaning: To die.

Origin: A theory suggests that when slaughtering a pig, it would be hung from a beam (sometimes called a bucket) and would kick the beam in its death throes.

11. A Piece of Cake

Meaning: Something easy.

Origin: The idiom possibly originates from the tradition of giving cakes as prizes in competitions, suggesting that winning was easy.

12. Barking Up the Wrong Tree

Meaning: Pursuing a mistaken or misguided course of action.

Origin: This comes from hunting dogs that might have barked at the base of the wrong tree after the prey in question moved.

13. Spill the Beans

Meaning: Reveal secret information.

Origin: An ancient Greek voting method used beans. A white bean indicated a positive vote, and a black bean a negative. If the container was knocked over, the votes would be prematurely revealed, or the “beans were spilled.”

14. The Whole Nine Yards

Meaning: Everything, the full measure.

Origin: The exact origin is disputed, but one theory is that WWII fighter planes had nine-yard ammunition belts. When a pilot used all his ammo on a target, he gave it “the whole nine yards.”
