Our everyday vocabulary is littered with terms, phrases, idioms, and concepts drawn from different contexts—such as medicine, science, sports, politics, etc.—often altered or reinterpreted. The military world is no exception, and every day we use phrases that originated in war contexts or that were popularized by soldiers. Let’s have a look at some examples!

1

ASAP

One of the most widespread phrases popularized by military use, this acronym originated not in the armed forces but in the dental hygiene field as part of a list of recommended abbreviations for secretaries. However, it was adopted by the military around the 1950s and widely used during the Korean War. While it was conceived to mean "as soon as practically possible", its use in the military context shifted its meaning to "immediately".

No man’s land

Have you ever described an ambiguous or unclear situation as "no man’s land"? Well, that phrase was initially used for actual land, and it is still used that way. Popularized during WWI as a descriptor of the barren land between opposing trenches, it had been in use for centuries for unoccupied or unclaimed wastelands, often in dispute among bordering jurisdictions. While we now often use it figuratively, it is used in its literal sense in conflict zones and territorial disputes.

3

Deadline

Our modern life is hectic and filled with deadlines, but these, although important, don’t usually pose a threat to our lives. The original deadlines, though, were a different story. The phrase emerged during the American Civil War, and it referred to the boundary lines drawn around prisoner camps. Any prisoner who crossed the line was instantly shot, effectively making it a ‘deadline’. Luckily for us, its meaning has shifted to reflect a time limit.

4

Cup of joe

If you ever wondered about the connection between coffee and someone named Joe, several theories claim to have the answer. The most popular one —although refuted by many historians— links it to Josephus "Joe" Daniels, famous for banning alcohol in the Navy, which allegedly popularized coffee as a substitute. A more likely theory points to the term ‘jamoke’ (a contraction of java + mocha), widely used in the military around the 1930s.

5

Feeling blue

The color blue has traditionally been associated with melancholy, but military men might have had a hand in popularizing this idiom. Though blue flags currently carry a different meaning in nautical terminology, they were once used as a sign of mourning. If a ship’s captain or other high-ranking officer died at sea, their ship would fly a blue flag and paint a blue band around the hull, a custom that intertwined the color blue with sadness.

6

AWOL

If we think about it, most of the time we say someone’s AWOL, a leave is not required. We are simply stating that we don’t know where they are or why they left. But the case is quite different for its military use. First recorded in the 18th century, it was used as a full phrase, although it eventually became an initialism around WWI and then an acronym around WWII. Still in use in the military, it carries a more dire meaning than in the civilian context.

7

Murphy’s law

"Anything that can go wrong will go wrong." All of us have invoked Murphy’s law at some point in our lives, but who’s Murphy? The answer takes us to a U.S. Air Force base and a series of rocket tests during the late 1940s. After several mishaps, aerospace engineer Edward A. Murphy famously exclaimed: "If there are two or more ways to do something and one of those results in a catastrophe, then someone will do it that way." Murphy’s frustration was later summarized at a conference as "Anything that can go wrong will go wrong", and the rest is history.

8

Roger

Most people wouldn’t be surprised to learn that this phrase is of military origin, but not many would be able to explain how it came to mean ‘understood’. During WWII, the American and British forces used the Able-Baker alphabet for radio communications, where Roger (and not Romeo) represented the R. ‘Roger’ meant your message had been received and understood. While most militaries later shifted to the NATO alphabet, the use of roger as ‘understood’ stuck and was popularized by its use in the Apollo lunar missions.

9

Got your six

While not as commonly used as other phrases of military origin, most people know that if someone tells them "I got your six," it means they have their back. The phrase stems from WWI aviators using the 12-hour clock face to describe directions: 12 o’clock was the front, 6 o’clock the back, and 3 and 9 o’clock the sides. As a blind spot, the back was a pilot’s most vulnerable area, so a wingman who ‘got their six’ was always appreciated.

10

Run amok

People telling a story about rambunctious children running amok would hardly imagine that this phrase has quite the violent origin. In Malay and Javanese cultures, amuk was used to describe warriors who launched frantic and violent attacks, often associated with a spiritual possession. The term was introduced into English by 16th-century European explorers, but it was Captain James Cook who popularized the phrase "run amok."

Aren’t we all a bit narcissistic? 12 terms we owe to Greek mythology


Published on June 25, 2026

We’ve already explored English words inspired by movies, or derived from the works of popular authors. But have you ever noticed how many everyday words go back to Greek mythology? Sure, we have the more obvious ones—like "narcissist" or "nemesis"—but you might find in this list terms that you didn’t know were so old. Read on!

1

Tantalizing

Remember the story of Tantalus? He was a king who tried to fool the gods and make them eat his son. Never a good idea! As punishment, he was condemned to eternal hunger and thirst, forever surrounded by water he couldn’t drink and fruit he could not reach.

Thus the verb and adjective "tantalizing" were born to describe situations where something is temptingly close, but frustratingly out of reach.

2

Achilles’ heel

We all have a weak spot, and that’s what we refer to when discussing an "Achilles heel." But why? As myth has it, Achilles, the greatest Greek warrior, became invincible after his mother dipped him in the River Styx as a baby.

However, his heel wasn’t submerged during this process. That became the only spot through which he could be wounded. And, of course, that was exactly where Paris shot him with an arrow after his victories in the Trojan War—leading to his death.

3

Midas touch

The moral of King Midas’s fable is: be careful what you wish for! This mythical king asked the god Dionysus to grant him the power to turn everything he touched into gold. It worked out well for him until he held his loved ones and transformed them into golden statues.

The term "Midas touch" usually has positive connotations, though. We use it to refer to a person whose efforts are frequently successful—not someone who jinxes each of them!

Pandora’s box

Pandora was the first human woman according to Greek mythology. One day she was set to watch a jar—not a box—her husband owned, which she was instructed to never open. But eventually, curiosity won over her.

When she opened it, out flew all the evils of the world. Today, the mistranslated expression "Pandora’s box" refers to any process that, once set in motion, leads to a chain of disasters.

5

Nemesis

In Greek mythology, delivering justice was the job of Nemesis. The goddess of retribution, she made sure that those who committed hubris (excessive pride) or wrongdoing were punished.

Today’s meaning of the noun derives from that. "Nemesis" first referred to that fatal flaw that might destroy one, which then evolved to be used about an opponent or rival who seems unbeatable and who might cause someone's downfall.

6

Echo

Before referring to a sonorous effect, this word was the name of a nymph. This chatty young creature was cursed by an irritated Hera to only repeat the last words spoken to her—a curse that obviously worked disasters for her relationships.

She faded away until only her voice remained. Her story was used to explain the physical phenomenon of sound being repeated, but also to describe any repetition or imitation.

7

Muse

In Greek mythology, the Muses were nine goddesses who presided over the arts and sciences, inspiring creativity in mortals. From epic poetry to music and dance, these ladies were the ultimate source of artistic ideation.

Today, "muse" refers to anyone or anything that sparks the same spirit. It could be a loved one, a beautiful landscape, or even a really good cup of coffee.

8

Fury

"Fury" was never linked to any peaceful or amiable personality—not even in Greek antiquity. Erinyes or Eumenides were raging, vengeful deities who punished criminals. In Roman mythology, these were translated as the Dirae or the Furiae.

The English language adopted these concepts from Latin, and transformed them into "dire" and "fury."

9

Clue

This word comes from the story of Theseus, the first person to escape the Minotaur’s labyrinth alive. Young Ariadna helped Theseus find his way out by following a ball of thread (a "clew" in Old English).

Thus the concept of "clue" came to mean anything that helps us solve a problem or mystery.

10

Morphine

Millennia before being a character in the blockbuster The Matrix, Morpheus was the name of the god of dreams. He was often depicted with poppies, the source of opium.

In the 19th century, a pharmacist studying the painkilling effects of opium derivates decided to give this substance the name "morphium," in honor of the mythical Greek figure.

11

Titanic

Image: Francisco Ghisletti

We are not here referring to the tragically sunken ship—although that one derives from this term. "Titanic" is an adjective that describes something enormous and powerful, such as the majestic ship at its time.

The term alludes to the Titans, enormous primordial gods who preceded the Greek Olympians and had enough power to upturn the Earth.

12

Narcissistic

Finally, a word that gets tossed around very liberally these days: Narcissist! Most of us know the myth of Narcissus, the handsome lad who fell in love with his own reflection and drowned as a consequence.

Countless authors throughout history used "Narcissus" in the same texts as "self-love," from Shakespeare to Byron to Baudelaire. Later, many theorists assigned varying meanings to "narcissism," ranging from healthy to disproportionate obsession with the self.
