We all know that brunch means breakfast plus lunch, or that Eurasia is used to refer to the connected European and Asian continents. But did you know that words like twirl, smog, or Texarkana are in the same category of portmanteaus or blend words?

Portmanteaus (from the French porte-manteau, ‘cloak-carrier’, a suitcase that opens in two equal parts) are terms formed by combining two or more words, their sounds, or their meanings. They were named by Lewis Carrol (the one from Alice in Wonderland) to explain the logic behind some odd words in his poem Jabberwocky: like a porte-manteau that you open in two parts, portmanteaus are opened to reveal two meanings. Let’s explore some common portmanteaus (and also some that are false).

1

Twirl

This word is used to talk about anything that spins or rotates, like someone doing a pirouette or moving their thumbs around each other. It is a term common in everyday language, but did you know it’s a blend of two words?

Yes, twirl comes from combining twist and whirl, both in sound and meaning. A twirl, then, is a rotation (twist) that happens rapidly (whirl). Something to think about the next time you find yourself twirling your thumbs.

2

Popsicle

The word ‘popsicle’ was originally the name of an ice pop brand started by Frank Epperson, who forgot a bucket of powdered lemonade on his porch and found it frozen the next morning. But how did the word ‘popsicle’ come to be?

This treat was originally called the "Epsicle ice pop", a combination of Epperson and icicle. Allegedly, Frank’s children started calling it a ‘popsicle’ (pop + icicle) and insisted the name be changed. In time, the brand became so popular that it became the usual term for any ice pop.

Texarkana

If you ever find yourself near the Texas-Arkansas border, you might find a city called Texarkana. In fact, you might find two cities called Texarkana, one in each state, both in the Texarkana Metropolitan Area.

It’s not clear who named them, but everyone agrees that Texarkana is a portmanteau for Texas-Arkansas-Louisiana. Both cities claim to have the same birth date, but we can debunk this: Arkansan Texarkana was founded a year before Texan Texarkana.

4

Contrail

First of all, what is a contrail? Contrails are the line-shaped clouds left by aircraft, missiles, or rockets as a result of engine exhaust vapor combining with low temperatures. The vapor of the engines condenses when it contacts the cold atmosphere, leaving a trail, so condensation + trail: contrail.

5

Endorphin

Sadly for couch potatoes everywhere, it is a proven fact that exercise makes you feel good. This is because, during physical exercise, our brain creates endorphins, which work as painkillers and mood boosters.

Why are these natural painkillers called this way? You might remember the word morphine, the name of a common opiate analgesic. Endorphins are endogenous, meaning they are created by our organism. Combine this word with an old spelling of morphine, endogenous + morphin: endorphin.

6

Sitcom

Any sitcom fan might tell you that the appeal of the genre is not about the narrative arcs but the funny situations the characters find themselves in.

This comedic format, originally produced for radio, was first called situational comedy. With time, it was combined into a portmanteau, situational + comedy: sitcom.

7

Parsnip

Let’s have a look at a false portmanteau. For centuries before sugar was brought to Europe, parsnips were used as a sweetener. Ancient Romans called them pastinaca, now part of their scientific name (pastinaca sativa). How did they come to be called parsnips?

It is a widespread belief that parsnip is a portmanteau for parsley + turnip, since parsnip leaves look similar to parsley, but this is not true. In Old French, parsnips were called pasnaie, a word that Old English adopted as pasnepe. The ending -nepe meant turnip, so in time, pasnepe evolved into parsnip. So, not a blended word, but one that you will find in many portmanteau lists.

8

Electrocution

Being electrocuted is not a pleasant experience, and the origins of the word are as gruesome as the thing described. In the late 19th Century, the state of New York adopted the electric shock as the standard form of capital punishment. Newspapers covering the first execution by this method mixed the words electric + execution, coining the portmanteau electrocution.

Lacking a judicial term to describe accidental deaths caused by electricity, electrocution came to be used for all incidents involving an electric shock.

9

Smog

Air pollution is an unfortunate reality in our current world, and words like smog are a byproduct of these environmental issues. The city of London has suffered from bad air quality and fog for many centuries, an issue only worsened by smoke during the Industrial Revolution.

This phenomenon, also called pea soup fog, eventually became known as smog, a portmanteau of smoke + fog. The term not only describes the greyish color associated with it, but also the smell produced by chemical contaminants.

10

Shepherd

Let’s end our list with a portmanteau nearly as old as the profession it names. In the English language, the word shepherd is recorded as early as the 12th Century, though it had been in use for many centuries before that. Middle English sceepherde comes from Old English scēaphyrde, a portmanteau for scēap (sheep) + hierde (herdsman, someone who keeps domesticated animals).

The original term was only used for animal keepers, but eventually gained the added meaning of ‘leader’ or ‘guide’. Lewis Carroll might have named portmanteaus in the 19th Century, but they have existed since the dawn of time.


The 12 longest-living animals on Earth (and how they cheat time)


Published on December 7, 2025

Nature doesn’t just create beauty, it crafts survival miracles. While most animals have short lives, a rare few have mastered the art of staying alive for centuries, even millennia. These aren’t just long-lived creatures; they’re nature’s ultimate time travelers. From the frozen depths of the oceans to the darkest corners underground, they’ve developed bizarre, brilliant strategies to cheat death. Get ready to meet 12 animals whose lifespans will absolutely blow your mind.

1

Antarctic Sponge (Anoxycalyx joubini)

Image: NOAA

Record age: up to 15,000 years

This unassuming sea sponge thrives in the freezing waters of Antarctica, where temperatures hover around 28.6 °F—so cold that biological processes hit the brakes. In such icy conditions, metabolism slows to a crawl, allowing these sponges to live for thousands of years.

Some have reached impressive sizes of over 3 feet tall and have been around since mammoths were still thundering across the tundra. They don’t move, they don’t stress, and they barely change, just quietly existing while centuries pass them by. Their secret to extreme longevity? Glacial patience, deep-sea stillness, and a lifestyle that redefines "low-maintenance".

Immortal Jellyfish (Turritopsis dohrnii)

Age: technically… infinite

This tiny jellyfish, no bigger than a fingernail—less than 0.2 inches—is like the ocean’s very own Benjamin Button. What makes it truly extraordinary is its ability to rewind its life story, flipping back to a youthful, juvenile stage whenever it wants. While it’s not completely invincible (predators and other threats are still very real), if left undisturbed, it can keep hitting the reset button on aging indefinitely, making it one of the most fascinating "time-benders" in nature.

Ocean Quahog Clam (Arctica islandica)

Record age: 507 years

In 2006, a special clam was discovered buried deep in the seabeds of the North Atlantic. Scientists were able to determine that it had been there since at least 1499—that’s centuries before the United States was even a thought! This ancient marvel, nicknamed "Ming", was able to perfect a slow-and-steady approach to life. Growing at a snail’s pace and barely budging, Ming’s sedentary lifestyle turned out to be a brilliant strategy for beating the clock. Who knew doing almost nothing could be the ultimate secret to longevity?

4

Greenland Shark (Somniosus microcephalus)

Record age: estimated 392 years

These sharks aren’t your average ocean cruisers—they can stretch over 20 feet long and weigh up to 2,200 pounds. But what’s really mindblowing is how slowly they move, like they’re in a permanent state of deep relaxation. Living in the icy Arctic waters, these giants don’t hit adulthood until they’re about 150 years old, and some can glide through the depths for nearly 400 years. Imagine that! These ancient swimmers were already around before America declared independence... and they are still out there, silently roaming the seas!

5

Bowhead Whale (Balaena mysticetus)

Record age: over 211 years

This whale is a true ocean giant, stretching up to 60 feet long and weighing a staggering 200,000 pounds. But what makes it stand out isn’t just its size but its age. Some of these majestic creatures carry harpoons from the 1800s still lodged in their skin, like walking history books. Just picture living so long that you’re literally carrying outdated technology embedded in your body—talk about being a time traveler of the seas!

6

Red Sea Urchin (Mesocentrotus franciscanus)

Record age: 200 years

Spanning the chilly Pacific coastline from California all the way up to Alaska, this spiky little ball—about 7 inches across—is full of surprises. It munches on algae and calls the deep, dark ocean its home, thriving at depths of up to 300 feet. Don’t let its size fool you: this prickly creature is a true elder of the cold seas, quietly outliving many ocean neighbors while keeping a low profile. A tough, slow-living veteran wrapped in spikes!

7

Koi Carp (Cyprinus rubrofuscus)

Record age: 226 years

Meet Hanako, a legendary Japanese koi who swam through life for an astonishing 226 years. Scientists discovered how old she was by studying the rings on her scales, much like counting the growth rings of a tree. These colorful, ornamental fish aren’t just symbols of good fortune; they’re also secret long-lifers with the potential to celebrate over two centuries of birthdays, as long as they get the right care and a peaceful pond to call home.

8

Seychelles Giant Tortoise (Aldabrachelys gigantea)

Image: Ryan Grewell

Record age: 190 years

Jonathan is a male tortoise living on the remote island of Saint Helena in the South Atlantic Ocean. He was born back in 1832, and he’s still happily chomping lettuce and soaking up the sun today. Weighing in at more than 400 pounds and measuring around 3 feet long, Jonathan holds the title of the oldest known living land animal on the planet. If he could share tales, they’d span nearly two centuries of history. Imagine that!

9

Lake Sturgeon (Acipenser fulvescens)

Image: See page for author, Public domain, via Wikimedia Commons

Record age: 152 years

This ancient-looking fish, with its whisker-like barbels, looking like a tiny underwater submarine, prowls the lakes of North America. It can reach an impressive length of up to 7 feet and weigh around 200 pounds. These slow-living creatures don’t rush into adulthood—they start breeding only around age 20—and then take their time cruising through life at a leisurely pace. Believe it or not, one legendary catch in Wisconsin was estimated to be over 150 years old!

10

Kakapo Parrot (Strigops habroptilus)

Image: Andreas Sjövall

Record age: over 90 years

This chunky, night-loving parrot from New Zealand is a true oddball—it can’t fly, snores like a grumpy grandpa, and smells like fresh flowers. Despite its quirks, this bird boasts an impressively long lifespan. Sadly, it teeters on the edge of extinction. The oldest known kakapo, affectionately named Richard Henry, lived 90 years, earning him the title of the charmingly eccentric elder statesman of the avian world.

11

Naked Mole Rat (Heterocephalus glaber)

Record age: 37 years

This tiny, kooky rodent—barely 3 inches long and just over an ounce in weight—could’ve been cast straight from a sci-fi apocalypse flick. Dwelling in vast underground colonies across Africa, it’s practically invincible to cancer, pain, and the usual effects of aging. Scientists are fascinated by this little marvel, even if it’s not winning beauty contests anytime soon. Its superpowers make it a star in longevity research!

12

American Lobster (Homarus americanus)

Record age: estimated 100+ years

Lobsters have a totally different rulebook than us when it comes to aging. They don’t really grow old; they just keep getting bigger and bigger. Some giant lobsters weigh over 40 pounds and stretch beyond 3 feet long. Their biggest threats? Not old age, but predators or the risky process of shedding their shells. In theory, they could live forever if left alone—but let’s be honest, not many get to enjoy a peaceful, lobster-sized retirement!
