12 common sayings that don’t mean what you think

We hear them daily and rarely question their meaning, but many popular sayings come from surprising origins—or mean something entirely different than we think. Some of these discrepancies are rooted in history, others in mistranslation, and more than a few in good old-fashioned misunderstanding. Here are 12 familiar phrases decoded and laid bare with real facts.

The original version, a 12th-century German proverb—_"The blood of the covenant is thicker than the water of the womb"_—suggests chosen bonds (like friendship or military brotherhood) are stronger than family ties, the opposite of how it’s used today. This shift in meaning likely occurred in later times, as the abbreviated form entered popular speech.

The full phrase is "Great minds think alike… and fools seldom differ." With the full version, the meaning turns ironic—it suggests that both geniuses and fools can agree just as easily, likely a warning against groupthink.

This proverb is often used to warn against dangerous inquisitiveness, but the full version—_"Curiosity killed the cat, but satisfaction brought it back"_—adds nuance. It suggests that the reward of knowing can outweigh the risks of curiosity.

The full phrase is "Jack of all trades, master of none, but oftentimes better than master of one." Originally, it praised versatility, not criticized it. The missing line completely flips the meaning, suggesting it’s often better to be well-rounded than narrowly skilled.

This phrase meant an impossible task—just like lifting yourself by your own shoelaces. First recorded in the 1800s, it mocked absurd self-starting efforts. But by the 20th century, American individualism had flipped its meaning into a motivational mantra.

The original phrase is "The proof of the pudding is in the eating," meaning you have to try something to know if it’s good. The modern shorthand makes little sense by itself and loses clarity but still hints at the original idea: results matter more than appearances.

There are competing theories about this phrase’s origin. The most common links it to boxing radio commentary, where a losing fighter is "saved by the bell" at the end of a round. Others trace it to 18th-century burial customs, when the fear of being buried alive led to coffins being rigged with strings tied to bells aboveground.

A popular myth claims the phrase "rule of thumb" stems from a law allowing men to beat their wives with sticks no thicker than a thumb. Fortunately, no such law ever existed. The phrase dates back to the 17th century and likely originated in trades where measurements were estimated using the thumb’s width or length.

One theory about the origin of "cold turkey" links it to the clammy, pale skin that some people experience during withdrawal, said to resemble cold turkey meat. However, a more likely explanation is that it combines the earlier idiom "talking turkey" (meaning to speak plainly) with "cold," used to describe something abrupt or blunt.

This phrase isn’t about feeling cozy—it refers to rope-strung beds from the 18th century. Back then, mattresses rested on a web of ropes that needed regular tightening. "Tight" meant the ropes were pulled firm to prevent the mattress from sagging.

Though it sounds mythological, this phrase comes from early 1700s theater. Playwright John Dennis invented a new thunder sound effect for his play. After the show flopped, another theater used the effect without credit. Dennis famously complained, "They will not let my play run, but they steal my thunder."

Before modern transportation, trade ships often got stuck in winter ice. So, smaller vessels were sent to break the ice and clear a path. Used since at least the 16th century, the original nautical context made it a natural metaphor for overcoming barriers.

Wars are typically waged between nations, but in 1932, Australia faced an unusual adversary: emus. After large numbers of these flightless birds invaded crucial farmland within Western Australia’s Wheatbelt, the government decided to intervene by sending soldiers armed with machine guns to reduce the emu population in the area. However, most attempts were ineffective at most, killing very few birds and costing thousands of dollars in supplies and ammunition.

As soon as the first shot was fired, the seemingly tame emu dispersed way beyond the range of the machine guns, and apparently switched to guerrilla tactics of sorts, avoiding all further military ambushes and frontal attacks while still feasting on the farmer’s crops. The government’s futile attempts were ridiculed and physical barrier methods to manage wildlife were preferred from then on. Sadly, they give no medals for having endured the Great Emu War.

In 1518, the town of Strasbourg, France, was gripped by a strange and inexplicable phenomenon - people suddenly began dancing uncontrollably in the streets. The dancing madness persisted for weeks, with some of the affected succumbing to exhaustion or even death. The authorities at the time did not know how to react, and some people even joined the dancers voluntarily, as they feared it was a punishment from Saint Vitus (and presumably wanted to stay on the safe side).

After many efforts to fight the strange epidemic, the dancing eventually subsided and people in the town could resume their normal lives. While theories range from mass hysteria to hallucinogenic substances and neurological disorders like Sydenham's chorea, the event remains a historical enigma that challenges our understanding of the human mind and collective behavior.

In 1908, a massive explosion flattened over 80 million trees in the remote Tunguska region of Siberia. The cause? A mysterious airburst, likely caused by the explosion of a meteoroid or comet in Earth's atmosphere. It is now estimated that the event had an explosive energy of 3 to 5 megatons, equivalent to over a thousand Hiroshima bombs. The resulting shockwave broke windows, and knocked people down hundreds of miles away, reaching an equivalent of an earthquake of 5.0 on the Richter scale in some areas.

A bright glow was observed in night skies in Asia and Europe for days after the event due to high-altitude ice particles that formed as a result of the explosion. For all its magnitude, the explosion left no visible crater and minimal debris beside the devastated forest. The Tunguska Event serves as a stark reminder of the potential cosmic threats that lurk in the darkness of space.

Miscommunication can often lead to chaos, but rarely on the scale witnessed in the Battle of Karánsebes in 1788. The Austrian army, at the time facing the Ottoman Empire, descended into total anarchy when two different scouting parties mistook one another for the enemy, fired on each other, and raised the alarm.

Making matters worse, the Austrian army was made of men of different nationalities who more often than not could not understand each other. All attempts to end confusion and the ensuing friendly fire on the part of the Austrian emperor himself were in vain, and after a while - deeply demoralized - he was forced to give the order of retreat. When the Ottoman army arrived two days later, they found an empty battlefield and were able to take the city of Karánsebes without any resistance.

In 1807, eight years before Waterloo, Napoleon Bonaparte had a humiliating defeat at the hands of a strange opponent - a horde of rabbits. During the celebrations that followed the Treaties of Tilsit - which effectively ended the war between the French and Imperial Russia - Napoleon’s chief of staff Alexandre Berthier had the idea of organizing a rabbit hunt to entertain its guests.

So far, nothing out of the ordinary for the time, but when the rabbits were simultaneously freed along the edges of a grassy field, instead of scattering as expected, all these fluffy beasts began running toward their amused hunters. But the fits of laughter didn’t last long, as the now-hunted hunters realized that there was nothing they could do to stop the relentless animals as they swarmed their positions and had no other choice than to flee. Some accounts state that Berthier had gathered around 3000 rabbits, so not even mighty Napoleon was a match for this unexpected army.

Apparently, the chief of staff's mistake was buying tame rabbits from local farmers, accustomed to being fed by humans, instead of trapping wild hares for the hunt. If we learned anything from the Great Emu War, the lesson is clear: never underestimate animals!

In the aftermath of the eruption of Mount Tambora in Indonesia - the largest in at least 1,300 years - 1816 became known as the "Year Without a Summer." The volcanic ash floating in the atmosphere led to climate abnormalities worldwide, resulting in crop failures and widespread famine in the most affected areas.

In Europe and North America temperatures plummeted, and most crops suffered irreparable damage due to the persistent frost. In the United States, a "dry fog" was observed in the eastern regions, dimming sunlight so much that sunspots were visible to the naked eye. Also, the high level of volcanic particles present in the atmosphere caused strange optical effects in the following years, such as strong red hues during sunsets, which can be observed in many paintings produced at the time.

It seems that wars against unusual adversaries are a fashionable trend in human history because the Roman Emperor Caligula declared war in the year 40 AD on no one other than the god Neptune himself, king of the raging seas.

Known for his eccentricity, Caligula allegedly ordered his legionnaires to "attack" the sea with swords and spears, after which he declared victory against the powerful god and told the men to gather seashells as trophies of war. One can only imagine that the soldiers had a fun -albeit puzzling- day.

In the late 1980s, Pepsi briefly possessed the sixth-largest navy in the world. In exchange for commercializing Pepsi products in the Soviet Union, the company received 17 submarines, a cruiser, a frigate, and a destroyer.

However, the fleet was composed of obsolete and unseaworthy vessels that were destined to be turned into scrap almost immediately. The payment was made in the only resources the USSR could gather easily at the time, and it provided a way to establish profitable international relations - and open up to the world.

The American Civil War started and concluded with a curious connection to Wilmer McLean, an American wholesale grocer from Virginia. The conflict's first major battle, the First Battle of Bull Run, took place in McLean's farm in 1861. A cannonball fell directly through the kitchen fireplace of the McLean’s house, which was being used as headquarters for the Confederate Army, destroying the dinner that was being prepared by the stationed officers - something that was noted not without humor by the Brigadier General P. G. T. Beauregard.

The McLean family moved to Appomattox, Virginia trying to escape the war, but just four years later, General Robert E. Lee surrendered to General Ulysses S. Grant in McLean's parlor, marking the conclusion of the Civil War. Unintentionally, McLean was a prime witness of one of America’s most defining conflicts. Later, he said of this: "The war began in my front yard and ended in my front parlor."

Genghis Khan's vast empire and brutal military campaigns had an unexpected impact on the Earth's climate. A recent study suggests that the Mongol invasions in the 13th century led to a significant reduction in global carbon dioxide levels, as large areas of cultivated land returned to forests.

This had the unintentional effect of scrubbing as much as 700 million tonnes of carbon from the atmosphere, roughly equivalent to the global annual consumption of gasoline today. This drastic ecological shift highlights the effect that land use, and particularly deforestation can have on our planet at a large scale.
