Making up language

Words that were invented by fiction writers, and now we all use them

Sometimes, preexisting words just don’t cut it for writers. So they invent new ones. That was the case for terms like utopia, robot, and nerd. Whether they grew to be used in philosophical texts or on playgrounds, they have certainly entered our vocabulary. Let’s take a look at 11 examples!

1

Nerd

The word has been many things, from a schoolyard insult to a badge of honor for having certain interests. It first appeared in Dr. Seuss’s 1950 book If I Ran the Zoo, where a strange creature called a "Nerd" appears among other fanciful beasts.

Seuss didn’t define it as brainy or awkward, but within a few years, the word was popping up in slang to describe socially inept people or bookworms.

Cyberspace

Today, when we say "cyberspace," we mean the intangible digital world we enter when we go online. But the word was coined by sci-fi writer William Gibson in his 1982 short story Burning Chrome.

Gibson later famously described cyberspace as a "consensual hallucination" shared by billions of connected users. The term predates the World Wide Web by nearly a decade, yet it foresaw the immersive, sometimes overwhelming, reality of living digitally.

Debunk

Today, when we say we have "debunked" a myth, we mean that we have exposed it as false. The word itself, however, originated as a literary invention in 1923, coined by American writer William E. Woodward in his book Bunk.

Woodward used debunk to mean stripping nonsense, or "bunk" of its dignity, a definition that closely aligns with how the word is still used today.

Robot

Today, we picture robots as everything from Roombas to humanoid androids, but the word itself dates back to a 1920 Czech play, R.U.R. (Rossum’s Universal Robots) by Karel Čapek.

The term comes from robota, meaning "forced labor" or "drudgery." In the play, however, the "robots" were not mechanical but biological constructs, closer to what we might now call clones. Both the term and the concept spread quickly across Europe and the United States, reaching the vocabulary of more and more writers.

5

Utopia

When we say something is "utopic," we mean it’s impossibly ideal. The term "utopia" was coined by Sir Thomas More in his 1516 book Utopia, where he described an imaginary island society with perfect laws, harmony, and equality.

But the trick was in the name: in Greek, ou-topos means "no place" while eu-topos means "good place." The word took off quickly, giving us not only "utopia" but also its darker twin, "dystopia," which would dominate much of modern literature.

6

Serendipity

Few words sound as delightful as what they mean, and "serendipity" is one of them. It refers to a happy accident, a lucky discovery made while looking for something else.

The term was coined in 1754 by Horace Walpole, a British writer and politician, inspired by a Persian fairy tale titled The Three Princes of Serendip. In the story, the princes are constantly making discoveries "by accident and sagacity."

7

Lumos

Fans of Harry Potter know Lumos as the spell that lights the tip of a wand. J. K. Rowling coined the word by drawing on Latin roots, such as lumen, meaning "light."

"Lumos" has since slipped into everyday use to the point that some smartphone voice assistants recognize it as a command to turn on a device’s flashlight.

8

Hobbit

The word hobbit instantly evokes images of small, hairy-footed inhabitants of the Shire, thanks to J. R. R. Tolkien. A trained philologist with a deep fascination for languages, Tolkien coined numerous terms, including hobbit and mithril, that have since entered popular culture.

The word became widely recognized even beyond The Lord of the Rings fan base. While hobbit originally referred to a fictional race in Tolkien’s legendarium, it is now sometimes used informally to evoke something small, cozy, or diminutive in character.

9

Tween

Today, we use tween to describe the awkward stage between childhood and adolescence, typically covering ages 9 to 12. The word itself, however, traces back to J. R. R. Tolkien, who first introduced the idea of "tweens."

In The Fellowship of the Ring, hobbits in their "tweens" were those between 20 and 33; no longer teenagers, but not yet considered fully adult in hobbit society. Marketers later borrowed the catchy term to describe human preteens, and it stuck.

10

Gossip

The word "gossip" feels inseparable from modern life. Yet it began as the Old English term godsibb, meaning a "godparent" or a close, trusted companion. It was Geoffrey Chaucer, in The Canterbury Tales, who helped nudge the meaning toward talk and chatter.

Over time, the term drifted further, shifting from "companion" to "idle talk" and, eventually, to its modern association with rumor and speculation.

11

Butterfingers

We all know what it means to be a butterfingers: clumsy, prone to dropping things, with hands seemingly as slippery as if coated in butter. This playful insult is often credited to Charles Dickens, who used it in his novel The Pickwick Papers to mock a character’s poor grip on objects.


Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

Treasured guest

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Code Adam

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

Code Blue

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Dr. Firestone

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

Code 10

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

Code Bravo

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

Code Alpha

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

10-33

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Signal 70

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Echo, Echo, Echo

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
