You won't believe where the word "dude" actually came from

Have you ever stopped to wonder where our everyday words actually come from? You might be surprised to learn that dude started as a way to poke fun at men who were too fastidious about their outfits. Or that we owe the word hello to Thomas Edison, who thought it was a much better choice than Alexander Graham Bell’s suggestion, "ahoy" for telephone calls. Even the word OK is the lone survivor of an 1830s game of misspelled phrases. Let's explore the hidden stories behind the words we think we know so well.

Picture New York City in the early 1880s. Back then, dude was used to describe a "fastidious man," essentially a guy obsessed with his clothes and appearance. Some researchers believe it was actually a shortened version of "Yankee Doodle," referring to the character in the famous patriotic song. It was also used to make fun of people following the "aesthetic" fashion craze of the 1880s.

In the late 1800s, a dude was any Easterner who showed up looking a little too clean in the Western region of the US. From this, we get the term dude ranch, which was first recorded around 1921 to describe ranches that hosted these city-dwelling tourists for pay. It wasn't until the mid-1960s, in African-American jargon, that dude began to lose its negative edge and became a way to refer to any male.

While it feels like it’s been around forever, hello is actually a relatively young word. Its first known appearance dates back to 1826, in a Connecticut newspaper. Linguists believe it grew out of words like "hallo" or "hollo," which were used as loud calls to get a ferryman’s attention across a river or to urge hunting dogs forward.

It’s often said that Alexander Graham Bell, the inventor of the telephone, wanted people to answer the telephone with "ahoy!", but American inventor Thomas Edison pushed for "hello" as a clearer option. His version caught on, and soon telephone operators were known as "hello girls," helping turn the word into the everyday greeting we still use today.

Have you ever stopped to wonder where the word OK comes from? It first appeared in 1839 as the unique survivor of US slang. During this time, it was a common joke to use abbreviations for phrases based on deliberate misspellings. For example, people would use "N.C." for "enough said" as if it were spelled "nuff ced," or "K.Y." for "no use" as if it were "know yuse." And "OK" was used for "oll korrect".

This term was later popularized during the 1840 presidential election by the "OK Club," supporters of Martin "Old Kinderhook" Van Buren, and stuck because it provided a practical way to authorize documents. In 1919, Woodrow Wilson used the spelling "okeh" under the mistaken belief that it came from a Choctaw word meaning "it is so," though there was no historical evidence to support this. That version was eventually replaced by the modern spelling "okay" appeared in 1929.

The word jazz first appeared in American English around 1912, and it actually started as baseball slang rather than a musical term. In those early days, sports writers in California used it to describe something "lively" or "energetic," which is a meaning we still carry today when we say we want to "jazz something up." It likely grew out of the 1860s slang word jasm, which meant energy, vitality, or spirit, or from even an older word, gism, which carried a similar meaning in the mid-1800s.

The term was first applied to a new style of music in Chicago in 1915, specifically referring to Tom Brown’s all-white band from New Orleans. By 1918, the word also began to mean "unnecessary talk" or "rubbish," and the famous phrase "all that jazz," meaning "et cetera," was eventually recorded around 1939.

The origin of this word is not clear, but what is certain is that in the late 1700s, a quiz wasn't a test; it was a person. It was slang for someone who acted or dressed differently from the rest. By the 1840s, this grew into a common schoolboy prank where students would play jokes at the expense of someone they considered a quiz. Eventually, the meaning shifted toward the idea of a "puzzling question" designed to make someone look a bit foolish.

Around 1852, the word was used to describe a brief examination of a student. These early quizzes were usually oral and were designed to be a "thorough review" of lectures. By 1853, medical schools even had "quiz classes," where a system of close questioning was used to help students become familiar with their subjects in a way they couldn't get anywhere else.

Where does the word dog come from? The answer is still a mystery. The word docga is traced in some English as a reference to a powerful breed of canine, but the roots of the term have not been found yet.

It has replaced the terms hound, related to the German word hund, and cur, related to the German word korren, for growling. However, by the 16th century, the word dog was adopted in many continental countries: French dogue, Danish dogge, and German Dogge. What is more, in Spanish, they use the word perro for dog, and it also has an unknown origin. Were these terms first used as slang or nicknames?

Back in the mid-1200s, the word boy didn’t mean a child at all; it was used for a "servant," "commoner," or even a "troublemaker." By around 1300, it could also mean a "rascal" or "young criminal," and only by the mid-1300s to 1400 did it start to be used for a male child.

Although there are a few theories, its exact origin is still unknown. Some link it to Old French and Latin words related to servants. Linguist Anatoly Liberman even suggests it may come from a mix of a sound for an evil spirit and a baby word for brother. In places like Ireland, Cornwall, and the American West, boy could simply mean man. From around 1600, it was also used for enslaved or servant men, no matter their age.

We are used to seeing the term bad as the direct antithesis of good. But has it always been like that? The answer is negative. The direct opposite of good was originally evil until the 1700s, and bad was used less frequently.

It also has no other language relations. It is believed to be from the Old English derogatory term baeddel and its diminutive baedling, meaning "effeminate man, hermaphrodite, predrast," which are probably related to baedan, meaning "to defile."

Another word in the ‘origin unknown’ category is big. The word was first registered in the 13th century in writings from northern England and the North Midlands, with a sense of "powerful; strong." It is believed to have roots in a Scandinavian source, where the term bugge means "great man" in Norwegian dialect_._

Big started to be part of the English daily vocabulary in the 1400s, meaning "of great size," "full-grown, grown up," or "important, influential, powerful". In the 1500s, the sense of "haughty, inflated with pride" was added, and by 1913, it was also used to mean "generous."

Around the 1300s, the word girl (spelled gyrle) meant "a child or young person," and it could refer to both boys and girls, although it was used more often for females. Its exact origin is unknown, but the Oxford English Dictionary suggests it may come from a lost Old English word (gyrele). This possible root is linked to similar words in Germany, Norway, and Sweden, all meaning "small child."

Over time, the meaning changed. By the late 1300s, girl began to mean specifically a female child. By the mid-1400s, it was also used for a young unmarried woman. In the 1640s, it could mean "sweetheart," and by 1826, old girl was used for women of any age.

The truth about your brain

You won’t believe what happens in your brain while you sleep

Your brain is one of the most powerful and mysterious organs in your body. It controls everything from your thoughts to your emotions and even processes information at lightning speed. But how much do you really know about it? Some long-believed myths about the brain have been debunked, while other surprising facts reveal just how incredible this organ truly is. Get ready to be amazed by these fascinating brain facts!

You’ve probably heard this one before, but it’s completely false! While it’s true that not all parts of the brain fire at the same time, imaging studies show that most regions are active throughout the day, even when we sleep.

Your brain is constantly working, controlling bodily functions and emotions, and processing information. So next time someone says you’re only using 10% of your brain, you can confidently tell them that’s just a myth!

Here’s a weird fact: While your brain processes pain signals from the rest of your body, it has no pain receptors of its own. This is why surgeons can perform brain surgery on conscious patients without causing them pain.

However, the membranes and tissues surrounding the brain do have pain receptors, which is why headaches and brain injuries can be so excruciating.

How come we have headaches if the brain has no pain receptors? Well, that’s because headaches are triggered by chemical activity in the brain, changes in nerves and blood vessels, and even fluctuating serotonin levels.

In some cases, hormones like estrogen can also play a role, which explains why migraines are more common in women.

Dreams are proof that your brain never rests! (Warning: this fact can make you feel exhausted.) While you sleep, your limbic system, that is, the part of the brain that deals with emotions, becomes especially active, which is why dreams often feel so intense.

On average, humans experience four to seven dreams per night, even if we don’t always remember them. And what about that scary nightmare about falling? Well, you can thank your amygdala, the brain’s fear center, for that one.

Have you ever walked into a room and instantly forgotten what you were after? That’s because short-term memory only lasts about 20-30 seconds! That’s not enough!

Your brain holds a limited amount of information in its active state before deciding whether to store it or discard it. Ironically, we can’t really choose what makes the cut, but we do hope these facts stay with you!

That sharp, icy pain when you eat something too cold? It’s your brain’s way of telling you to slow down! Officially called sphenopalatine ganglioneuralgia, a brain freeze happens when cold food or drinks rapidly chill the blood vessels in your throat, causing them to constrict and then rapidly expand. This sends pain signals to your brain, warning you of the sudden temperature shift. It’s annoying, but it’s actually your body trying to protect itself!

You didn’t need us to tell you, but let’s look at the details: The average person has between 12,000 and 60,000 thoughts per day. What’s even more interesting? 95% of those thoughts are the same ones you had yesterday. Is that not surprising enough? Hear this out: 80% of them tend to be negative. That’s because our brains are wired for survival, constantly analyzing risks and potential dangers.

Even though it only makes up about 2% of your body weight, your brain employs a major quantity of energy! It consumes 20% of your oxygen and blood supply, making it one of the most demanding organs in your body.

If your brain goes without oxygen for just five minutes, brain cells start dying, leading to irreversible damage. This is why deep breathing and cardiovascular exercise are great for brain health!

Do you know that feeling when you hit the back of your head and see stars? That’s because your occipital lobe, which controls vision, is located at the back of your brain. If you get hit there, your brain momentarily misfires, causing flashes of light.

Interestingly, your brain processes vision on the opposite side; while your right brain controls your left eye, your left brain controls your right eye. It’s one of the many ways the brain operates in a complex way.

Believe it or not, your brain generates between 12 and 25 watts of electricity when you’re awake. If you can’t really grasp how powerful that is, check this out: It’s enough to power a small light bulb! Your brain’s electrical activity is what allows neurons to send signals at speeds of up to 260 miles per hour.

Your brain may be the fattiest organ in your body, consisting of at least 60% fat! This is why consuming healthy fats, like omega-3s and omega-6s present in fish, for example, is essential for brain health.

Healthy fats stabilize brain cell walls, reduce inflammation, and support cognitive function. So go ahead and enjoy that avocado toast, it’s food for your brain!

It’s not just your memory that fades over time; the brain itself physically shrinks as one gets older. It continues developing until your late 40s, but after that, it slowly decreases in size.

Now, size doesn’t equal intelligence, so a smaller brain doesn’t necessarily mean a less capable one. Staying mentally active, exercising, and eating brain-boosting foods can help keep it in top shape!

We often think of cholesterol as bad, but your brain actually depends on it! In fact, 25% of your body’s cholesterol is stored in your brain, where it helps with learning and memory. However, unlike other organs, the brain can’t absorb cholesterol from the blood, it has to produce its own. So, while too much cholesterol in the body can be harmful, the right amount is vital for brain function. At least you can use that as an excuse to get that burger!
