How 20 Animals Got Their Names

The word animal derives from a Latin word for a "breath" or "soul," anima. Although it first appeared in English in the late 14th century, it remained fairly uncommon until the 1600s, when its use as a replacement for the older word beast—which once referred to any living creature, but today has wilder, more ferocious connotations—won out. Beast, in turn, was adopted into English from French sometime around the early 1200s. But just as it was eventually superseded by animal, beast itself took over from deer, which was used fairly loosely in Old English to refer to any wild animal.

Put another way, the history of animals and beasts is all a bit confusing—though thankfully, the individual names of different kinds of animals aren’t nearly as mixed-up. That’s not to say they don’t have their own stories to tell, though.

1. Penguin

No one is entirely sure why penguins are called penguins (not helped by the fact that they were once upon a time called arsefeet), but the best theory we have is that penguin is a corruption of the Welsh pen gwyn, literally “white head.” The name pen gwyn originally applied to the great auk, an enormous flightless black-and-white seabird of the North Atlantic, and it's presumed that sailors to the South Atlantic either confused the flightless black-and-white seabirds they saw there for auks, or just used the same word for both creatures.

2. Albatross

This is a strange one: In the 16th century, the Arabic word for a sea eagle, al-ghattas, was borrowed into Spanish and became the Spanish word for a pelican, alcatraz (which is where the island with the prison gets its name). Alcatraz was then borrowed into English and became albatross in the late 17th century—but at each point in history, the word applied to completely different animals. An alternative theory claims that albatross and Alcatraz might actually be unrelated, and instead, albatross could be derived from a Portuguese word, alcatruz, for one of the troughs that carried the water around a waterwheel. Even if that’s the case, however, the word still probably began life as another name for a pelican, with the bucket of the waterwheel probably alluding to the pelican’s enormous bill pouch.

3. Rhinoceros

Rhinoceros literally means “nose-horned.” The rhino– part is the same as in words like rhinoplasty, the medical name for a nose job, while the –ceros part is the same root found in words like triceratops and keratin—the tough, fibrous protein that makes up our hair and nails and rhino horns.

4. Ostrich

The English word ostrich is a corruption of the Latin avis struthioavis meaning “bird” and struthio being the Latin word for the ostrich itself. In turn, struthio comes from the Greek name for the ostrich, strouthos meagle, which literally means “big sparrow.”

5. Hippopotamus

A hippo with its mouth open

Hippopotamus literally means “river horse” in Greek. It might not look much like a horse, but it certainly lives in rivers—and let’s be honest, it looks more like a horse than an ostrich looks like a sparrow.

6. Raccoon

Raccoon is derived from an Algonquin word that literally means “he scratches with his hands.” Before that was adopted into English, raccoons were known as “wash-bears” (and still are in several other languages, including Dutch and German), which refers to their habit of washing their food before eating it.

7. Moose

Moose, too, is thought to be an Algonquin word, literally meaning “he strips it off,” a reference to the animal’s fondness for tearing bark off trees. Likewise, muskrat is perhaps a derivative of an Algonquin name meaning “it is red.”

8. Tiger

Our word tiger goes all the way back to Ancient Greek, but the Greeks in turn borrowed the word from Asia, and it’s a mystery where the word actually originated. One theory is that it comes from tighri, a word from Avestan (an ancient Iranian language) that literally means “arrow” or “sharp object,” but that’s only conjecture. Speaking of big cats …

9. Leopard

Confusingly, leopard literally means “lion-panther” or “lion-leopard.” Variations of the word pard have been used to mean “leopard” or “panther” since the days of Ancient Greek, while leon was the Greek, and eventually Latin, word for a lion. The word lion itself, meanwhile, is so old that its origins probably lie in the impossibly ancient languages from which Egyptian hieroglyphics derived. Another confusing big cat name is …

10. Cheetah

Cheetah on the hunt

It derives from chita, which is the Hindi word for “leopard” and in turn probably comes from a Sanskrit word literally meaning “spotted.”

11. Python

In Greek mythology, the Python was an enormous dragon-like serpent that was slain by the legendary hero Apollo. Apollo left the serpent’s corpse to rot in the heat of the sun, and the site of its death eventually became the site of the oracle of Delphi (known as Pytho, to the Ancient Greeks). Ultimately, the name python itself derives from a Greek word literally meaning “to rot.”

12. Anaconda

The anaconda’s name is a lot harder to explain. Although anaconda are only found in South America, it’s likely that the name was brought there from elsewhere. One likely theory claims that it might once have referred to an enormous snake of southeast Asia that was known by a Tamil name, anaikkonda, literally meaning “having killed an elephant.”

13. Hyena

The name hyena traces back to the Greek word for a pig or a boar, hys, which apparently refers to the spiny hairs on the animal’s back.

14. Walrus

Walrus was borrowed into English in the 18th century from Dutch, but it may have its origins in the Old Norse word rosmhvalr, which came from another name for walrus, morse. Before then, walruses were known as sea-elephants, sea-oxen, sea-cows, and even sea-horses.

15. Panda

A panda in a tree

Panda was borrowed into English in the early 1800s, when it originally referred exclusively to what we’d now call a red panda; in reference to the giant black-and-white panda, the word only dates back to the beginning of the 20th century, when it was erroneously thought to be related to the red panda. Either way, panda is thought to come from a Nepali word, Nigálya-pónya, that might literally mean something like “cane-eating cat-bear.”

16. Octopus

Octopus literally means “eight-footed” not, despite what many people think, “eight-armed” or “eight-legged.” Also contrary to popular belief, the plural of octopus really isn’t octopi. It would be if octopus were a Latin word (in which case its plural would follow the same rules as words like fungi and alumni), but octopus is actually derived from Ancient Greek roots. So to be absolutely, pedantically correct, the plural of octopus should be octopodes—but why complicate things? Feel free just to call more than one octopus a group of octopuses.

17. Tortoise

No one is entirely sure why tortoises are called tortoises, although it’s fair to say that none of the theories we have to choose from is particularly flattering. On the one hand, tortoise might be a derivative of a Latin word, tartaruchus, literally meaning “of the underworld.” On the other, it might come from the Latin tortus, meaning “twisted” (which is also where the adjective tortuous derives from). The actual Latin name for the tortoise, testudo, was much simpler, however: it simply means “shelled.”

18. Meerkat

The name meerkat was borrowed into English from Afrikaans, the Dutch-origin language spoken in South Africa. In its native Dutch however, meerkat is another name for the guenon, a type of monkey found in sub-Saharan Africa. How did the two words become confused? No one knows.

19. Kangaroo

There’s an old folk etymology that claims kangaroo means “I don’t know.” According to the story, on his arrival in Australia, Captain Cook asked a native Australian what the bizarre looking creatures bounding around in the distance were. He replied, in his native language, “I don’t know”—which, to Captain Cook, sounded something like “kangaroo.” It’s a neat story, but likely an apocryphal one, not least because the chances of a native Australian not knowing what a kangaroo was are pretty slim. Instead, it’s likely kangaroo likely derives from a local Guugu Yimidhirr word, perhaps simply meaning “large animal.”

20. Platypus

A platypus swimming

And lastly, staying in Australia, the duck-billed platypus’s name literally means “flat-footed.” Bonus fact: Because of its bizarre appearance, the platypus was also once known as the duck-mole.

This list first ran in 2016.

Pandemic vs. Epidemic: What’s the Difference?

As the new coronavirus continues to spread around the world, the words epidemic and pandemic are showing up in news reports more often than they usually do. While the terms are closely related, they don’t refer to the same thing.

As the Association for Professionals in Infection Control and Epidemiology (APIC) explains on its website, “an epidemic occurs when an infectious disease spreads rapidly to many people.” Usually, what precedes an epidemic is an outbreak, or “a sudden rise in the number of cases of a disease.” An outbreak can affect a single community or several countries, but it’s on a much smaller scale than an epidemic.

If an epidemic can’t be contained and keeps expanding its reach, public health officials might start calling it a pandemic, which means it’s affected enough people in different areas of the world to be considered a global outbreak. In short, a pandemic is a worldwide epidemic. It infects more people, causes more deaths, and can also have widespread social and economic repercussions. The spread of the Spanish influenza from 1918 to 1919, which killed between 20 and 40 million people around the world, was a pandemic; more recently, the H1N1 influenza created a pandemic in 2009.

Here’s where it gets a little tricky: There’s no cut-and-dried classification system for outbreaks, epidemics, and pandemics. Based on the definitions above, it might seem like the current coronavirus disease, now called COVID-19, falls into the pandemic category already—according to a map from the World Health Organization (WHO), there are more than 80,000 confirmed cases in 34 countries, and nearly 2700 people have died from the disease. It’s also beginning to impact travel, stock markets, and the global economy as a whole. But WHO maintains that although the situation has the potential to become a pandemic, it’s still an epidemic for now.

“It really is borderline semantics, to be honest with you,” Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN earlier this month. “I think you could have people arguing each end of it. Pandemics mean different things to different people.”


You’re Probably Pronouncing Nevada All Wrong

As people around the United States were checking who won the Nevada caucus this weekend, many were faced with a different question: How exactly do you pronounce Nevada?

The case of Ne-VAH-duh versus Ne-VAD-uh was thrust into the spotlight recently as candidates for the Democratic presidential nomination toured the state, but the controversy isn't new. George W. Bush and Michelle Obama have been accused of mangling the pronunciation, and in 2016, Donald Trump incorrectly told Nevada residents they were pronouncing the name of their own state wrong. The subject is so sensitive to Nevadans that Nevada Governor Brian Sandoval sent a text to former candidate for the Republican presidential nomination John Kasich instructing him how to say the word.

So what is the right way to say Nevada? University of Nevada in Las Vegas associate history professor Michael Green told The New York Times that Ne-VAD-uh (with the second syllable rhyming with mad) is the standard pronunciation with locals, while saying Ne-VAH-duh (second syllable rhymes with spa) will expose you as a foreigner to the state.

The reason for the confusion may be that Nevada is a Spanish word. Meaning “snow-capped,” Ne-VAH-duh would be the correct pronunciation if you were to say the name in its original tongue. But following a flood of Northern and Midwestern settlers to the state in the 1860s, the hard a prevailed.

Not everyone in Nevada agrees there's one true pronunciation. In 2010, a Las Vegas assemblyman introduced a bill that would have officially made Nev-AH-da an acceptable alternative. The resolution never made it off the ground, and using the Spanish pronunciation will still get you funny looks in the state today—especially if you're a politician.
