The English language is filled to the brim with impactful, deep, and sometimes whimsical imagery: Have you ever stopped to think about how much we rely on a vast array of unusual phrases to relay very common concepts? We are of course talking about idioms, those quirky and eccentric sentences that, if anything, provide a bit of color and variety to our everyday lives. But have you wondered where the idioms we say daily come from? Who was the first person to warn someone not to look into a gifted horse’s mouth? Don’t worry, we got you covered: We have researched the origins of 10 of the most common idioms in the English language. Enjoy!
Fly off the handle

The idiom "to fly off the handle" is used to describe someone who is not in full control of their emotions: Someone might fly off the handle if they angrily and suddenly overreact to a minor inconvenience.
You might be inclined to think that the titular handle is one found in an everyday tool like a frying pan or a wok, but it in fact comes from the world of lumberjacks: According to historians, this idiom comes from badly manufactured axes, out of which poorly fastened axe heads would sometimes come off flying. Since this outcome is obviously dangerous, this idiom perfectly describes unpredictable and potentially unpleasant situations.
Chew the fat

This idiom is a bit off-putting, isn’t it? Someone "chewing the fat" is engaged in pleasant yet trivial conversation: Whether it is idle chit-chat or harmless gossip, two (or more) people chewing the fat are usually chatting without a care in the world.
If you are wondering how chewing fat would eventually morph to mean chatting, you might want to take a look at the world of 19th-century sailors. In the days before refrigerators, sailors had to carry food that wouldn’t spoil on their voyages: One of these items was salted pork skin, which largely consisted of fat. In due time, the idle chatter that came from the long time it took to consume this honestly disgusting food became synonymous with the action itself.
Once in a blue moon

This is one of the idioms on this list that makes the most sense. An astrological blue moon is a rare occurrence in which the second full moon of a month might be seen with a pale blue tint. Blue moons usually occur approximately every 3 years, although some phenomena like volcanic eruptions or forest fires might produce them as well.
Logically, the idiom "once in a blue moon" is used to describe something that happens very rarely. In any case, this idiom does bring a certain mystique to complaining about that friend who is never able to hang out: You can simply say that they come around "once in a blue moon".
Give the cold shoulder

No one wants to be on the receiving end of a "cold shoulder": This idiom is used to describe someone who is intentionally unfriendly to someone else. From an angry friend to a disgruntled coworker, if anyone is giving you the cold shoulder, you might want to look into what made them mad in the first place.
You might be inclined to believe that the origin of this idiom comes from the action of literally turning away from someone. However, some historians have a more interesting theory: They believe that it comes from medieval etiquette. According to these linguists, whenever the host of a dinner party in medieval times wanted their guests to leave, they would serve a cold cut of pork or mutton shoulder.
Till the cows come home

Isn’t this idiom adorable? We instantly think about a worried cow waiting for her teenage cows to come home only to scold them for being out past their curfew. In any case, the idiom "till the cows come home" is used to describe something that takes a long and indefinite amount of time.
As you would expect, this idiom comes from the world of farming, and it dates back to at least the 1500s. Since cows were often milked late at night, the last job a farmer would have to do before turning in for the night would be to return the cows to their barns. And, as anyone with an office job will attest, the last task of the day often seems like the longest.
Blood is thicker than water

The idiom "blood is thicker than water" is regularly used to highlight the importance of family, where blood is used as a symbol of family bonds. When someone tells you this idiom, they are trying to remind you that family needs to stick together through thick and thin.
Curiously, some historians believe that the origins of this idiom can be traced back to a mistranslation. According to them, the full adage states: "The blood of the covenant is thicker than the water of the womb". Therefore, if this theory is to be believed, the meaning of this idiom would be the exact opposite, and bonds of friendship would supersede family bonds.
Let the cat out of the bag

This idiom should be fairly self-explanatory: Unless they are about to go on a delightful walk through the park, cats should never be placed inside bags. Not that this reminder will do anyone any good: As every single cat owner can attest, cats can (and will) go inside any object they find even slightly suitable.
In any case, what’s the origin of the idiom "to let the cat out of the bag"? Well, the answer might lie in Medieval markets, of all places. According to one theory, some unscrupulous merchants might trick patrons into buying small kittens, passing them as piglets sold inside a bag. Once the titular cat was "let out of the cat", the enraged patron would realize they were bamboozled, at which point it would probably be too late.
By and large

"By and large" is an idiom used to describe a situation in general: For instance, you might be complaining about your job, only to end your sentence by saying "But by and large, I think it is a good workplace".
As with many other English idioms, "by and large" comes from sailor slang. In the old days, sailors would use the nautical term "full and by" to refer to traveling into the wind, while "large" was used to describe the exact opposite: Wind coming from behind. In that sense, the term "by and large" emerged to describe a situation in which the wind was coming from all directions.
White elephant

The idiom "white elephant" is used to describe something lavish and expensive that however doesn’t seem to serve any function whatsoever, rendering it burdensome. This phrase might seem nonsensical, but it does make perfect sense when you think about it: Would you like to receive a costly elephant as a birthday present?
You might think we are joking, but this is actually the historical basis behind this idiom: According to historians, rulers of the Kingdom of Siam (now present-day Thailand) would gift white elephants as gifts. However, you might be surprised to learn that these outlandish gifts were actually punishment: Since the elephants were extremely costly to keep, they would often become financial burdens to their owners.
Cat got your tongue

We’ll end this article with one of the most baffling idioms we were able to find. The idiom "cat got your tongue" is used to describe someone rendered speechless after learning a particularly shocking piece of information. However, why these adorable pets are associated with losing the ability to speak is a mystery we can’t stop thinking about.
And while we can’t provide you with a definitive answer, here are some plausible theories: Some believe that it refers to Medieval times, in which blasphemers would be punished by forcefully removing their tongues and feeding them to street cats and other vermin. Others believe that it comes from the fear of witches, who would supposedly command their cat familiars to hex and curse their victims, rendering them speechless and catatonic.
