The Strange Origins of Everyday Phrases We Still Use

We use them every day without a second thought. Phrases like “bite the bullet,” “break the ice,” or “let the cat out of the bag.” Yet the origins of everyday phrases are surprisingly colorful (and sometimes dark) and trace back centuries. 

Each saying carries a little piece of history, passed down through generations, often long after its literal meaning has faded. Here’s the fascinating story behind ten everyday phrases that reveal just how strange and vivid language can be.

“Bite the Bullet”

Before the invention of anesthesia, soldiers wounded in battle often had to endure surgery while fully conscious. To cope with the excruciating pain, they were given a bullet to bite down on. Typically, something firm but not sharp enough to cause harm. Over time, the phrase came to mean facing a difficult situation with courage or endurance. Today, “biting the bullet” doesn’t involve actual bullets—just bravery.

“Break the Ice”

In the days before modern transportation, ships sometimes got trapped in frozen harbors during winter. Smaller vessels called icebreakers were sent ahead to clear the way, literally “breaking the ice” so others could follow. Later, the phrase took on a social meaning, referring to helping people feel comfortable and start a conversation. So next time you make small talk, you’re metaphorically captaining an icebreaker.

“Let the Cat Out of the Bag”

This curious phrase likely comes from medieval marketplaces, where piglets were sold in sacks. Unscrupulous sellers might substitute a cat instead, only for the deception to be revealed when the bag was opened—literally letting the cat out. The expression evolved into its modern meaning: to reveal a secret, especially one best kept hidden.

“Saved by the Bell”

Though it sounds like something from a boxing ring, the expression actually has two potential origins. In 19th-century England, safety devices were sometimes added to coffins in case someone was mistakenly buried alive. A string attached to a small bell allowed the “corpse” to signal for help, hence, being “saved by the bell.” Whether this ever truly saved anyone is debated, but the phrase endured and later became popular in boxing and pop culture.

“Raining Cats and Dogs”

This bizarre image of falling animals dates back to 17th-century England, when heavy storms sometimes washed dead animals through streets with poor drainage. The sight must have been grim, but it gave rise to one of the most enduring idioms in the English language. Thankfully, today it just means “raining heavily,” not a morbid weather report.

“Kick the Bucket”

The phrase ‘dying’ has an unexpected domestic origin. In old English slaughterhouses, animals were often hung from a beam or bucket while being killed. When the animal struggled, it would literally “kick the bucket.” Later, the phrase was applied to humans as a somewhat humorous euphemism for death. It’s a grim image wrapped in linguistic charm.

“Caught Red-Handed”

This expression originates from 15th-century Scottish law. If someone was caught with blood on their hands after committing a crime—usually poaching or murder—they were said to be “caught red-handed.” The phrase was first recorded in legal documents around 1432, but it’s survived into modern times as a metaphor for being caught in the act.

“Under the Weather”

Sailors coined this one. In rough seas, ill or seasick sailors were sent below deck—literally under the weather—to recover away from the storm. Over time, the phrase broadened to mean feeling sick or out of sorts in general, even when far from the ocean.

“Barking Up the Wrong Tree”

This phrase comes from 19th-century America and the world of hunting dogs. When raccoons or other prey escaped into trees, dogs sometimes barked at the wrong one after the animal had already fled. The saying perfectly captures the idea of pursuing the incorrect lead or making a mistaken assumption.

“The Whole Nine Yards”

The origin of this one is still debated, but one of the most convincing theories points to World War II fighter pilots. The ammunition belts for machine guns on fighter planes were about nine yards long. If a pilot used all of it in a single burst, he’d given the enemy “the whole nine yards.” Over time, the phrase evolved to mean going all in or giving your full effort.

The Living History of Language

Idioms like these are more than quirky turns of phrase. They’re living fossils of culture, work, war, and everyday life. Each one captures a story about how people once lived, struggled, and joked. While the original meanings may fade, the phrases endure, linking us to centuries of human experience in just a few words.

So the next time you “bite the bullet” or “break the ice,” remember: you’re carrying on a centuries-old linguistic tradition. These phrases serve as proof that language, like history, never really dies.
