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.

Secret uses

There’s a hidden microphone in your phone, and here’s where it is

You’ve probably twisted a bread bag closed, filled up your car, or pulled a sheet of aluminum foil from the box thousands of times without giving it a second thought. But many of the everyday objects we’ve used for decades have clever features that most people never notice. From the tiny pocket on blue jeans to the little arrow next to your gas gauge, these hidden designs have practical stories behind them, and once you know them, you’ll never look at these familiar items the same way again.

If you own an iPhone, you’ve probably noticed the tiny black dot next to the rear camera. It’s small, so people tend to assume it’s another camera sensor or even part of the phone’s design. The small hole found near the camera bump on every iPhone is actually a rear microphone.

It captures clearer audio when you’re recording videos and helps reduce background noise during FaceTime and regular phone calls. If you own an iPhone Pro model from the iPhone 12 Pro onward, you'll also see a larger dark circle. That’s the LiDAR scanner, which sends out invisible infrared light to create a 3D map of your surroundings. It helps the camera focus faster in low light, powers Apple’s Measure app, and makes augmented reality features much more accurate.

Whether it's a holiday dinner, an anniversary, or simply a nice meal with friends, you’ve probably held a wine bottle and noticed the deep indentation in the bottom. Many people tend to think the deeper the indent, the fancier the bottle.

That indentation is called a punt, and it’s been a part of the bottle-making for centuries. Originally, it helped strengthen hand-blown glass bottles, making them less likely to crack under pressure. Today, it still adds structural stability, particularly for sparkling wines, while also giving servers a comfortable place to rest their thumb when pouring, though some say it helps collect the sediment as wines age. In any case, a deeper pun doesn’t automatically mean a better or more expensive bottle.

Almost every driver has experienced that awkward moment at the gas station. You pull up to the pump, step out of the car, and suddenly realize the fuel door is on the opposite side.

To help prevent exactly that situation, many modern vehicles include a small arrow next to the gas pump symbol on the dashboard’s fuel gauge. The arrow points towards the side of the vehicle where the fuel filler door is located. It’s a small detail on the dashboard, yet once you notice it, you’ll never have to circle the pump again.

All elevators look pretty much the same. Bigger or smaller, they all look similar, a gray box with a mirror and buttons. But if you pay close attention, you may notice there’s a small round opening near the top of the door.

That opening is a keyhole used by trained maintenance technicians and emergency responders. With a special elevator key, they can manually unlock the landing doors when repairs are needed or if passengers become trapped inside. The system allows professionals to reach the elevator safely without damaging the doors or relying solely on electrical controls. Hopefully, most of us will never need to see it in action. But in an emergency, that tiny opening becomes one of the most important parts of the system.

If you’ve ever stood in the bread aisle comparing loaves, you’ve probably noticed the colorful plastic clips or twist ties holding the bags shut. Contrary to what many think, they’re not simply a part of the packaging.

For many bakeries and grocery stores, the colors indicate the day a loaf was delivered or baked. While the exact color schedule can vary between bakeries and regions, employees use the system to quickly spot older inventory and rotate fresher bread to the back of the shelf. That way, customers are more likely to pick up the freshest loaf available.

Whether you wear jeans every day or only pull them out for yard work, you’ve probably noticed the tiny extra pocket tucked inside one of the front pockets. It’s too small for a phone and not very useful for loose change, but there’s a reason for it.

Back in the 1800s, when Levi Strauss & Co. created rugged denim pants for miners, ranchers, and cowboys working across the American West, pocket watches were commonplace. Workers needed a safe place to carry their watches while riding horses, so that little pocket was designed specifically to protect the watch from damage. Pocket watches disappeared, but the tiny pocket became such an iconic part of blue jeans that manufacturers have continued including it for well over a century.

Almost everyone has had the same frustrating experience. You pull on a sheet of aluminum foil, and suddenly the entire roll slides out of the box and lands on the kitchen counter.

That’s exactly why major manufacturers such as Reynolds introduced the small side tabs, known as end locks, in the mid-1990s. By pressing the tabs inward, they hold the cardboard roll in place like built-in axles. This keeps the roll from sliding out of the box, makes it much more stable as you pull, and helps the serrated edge cut a cleaner, straighter sheet. It also reduces waste by preventing the foil from bunching up or tearing unevenly. It’s a simple design, yet useful as it can get.

Every household has pens lying around for all kinds of purposes. And most of them have a common feature, a hole in the cap, which isn’t simply part of the design.

BIC and other pen manufacturers included the opening as a safety feature. If someone, especially a child, accidentally swallows a pen cap, the hole can allow a small amount of air to pass through, reducing the risk of complete airway blockage while emergency help is on the way. The design became part of border efforts to improve consumer product safety after choking incidents drew attention to the danger of small plastic objects.

If you grew up sewing or watching somebody do it, you probably remember the classic tomato-shaped pincushion sitting beside the sewing basket. Hanging from it was a tiny red strawberry that looked like nothing more than a cute finishing touch.

In reality, that little strawberry has its own job. Instead of soft stuffing, it’s filled with emery, a gritty material made from crushed abrasive minerals. Running pins and needles through it helps polish away tiny spots of rust, smooth rough edges, and keep the points sharp enough to glide through fabric more easily.

Think back to the first time you learned to type. Maybe it was at work, or on a family computer. Wherever it was, someone probably told you to keep your fingers on the "home row." That’s exactly why the F and J keys have tiny raised ridges.

The bumps let your index fingers find the correct starting position by touch alone, allowing you to type without constantly looking down at the keyboard. The technique, known as "touch typing," is widely credited to American court stenographer Frank Edward McGurrin, who demonstrated it in 1888. As typewriters became more common, manufacturers experimented with different ways to help typists orient their hands, and by the mid-20th century, companies such as IBM standardized the subtly raised plastic bars that remain on nearly every keyboard today.
