Field guide · 16 words, five arrivals
Every animal name in English arrived at a date. Some were already in the language when it was first written down, and a few of those are older than writing. Others were coined by scholars out of Greek, carried home in a ship's log, or assigned last century by two zoologists following a rulebook. Put the names in the order they arrived and a pattern shows: each century named animals the way it met them.
This page follows sixteen animal name origins up that timeline, from bear to a species described in 1998, with each word split into the pieces it was built from. Three impostors are pulled out along the way: names that were wrong on the day they were given and stuck anyway. At the end, the six most literal names are loaded into the hybrid animal generator, which builds a camel-leopard or an earth-pig exactly the way the name says.
“The sort which is in the greatest Plenty is the Kangooroo or Kanguru, so called by the Natives; we saw a good many of them about Endeavour River.”
James Cook, journal of the Endeavour, August 1770
Already here
Before 1066
The oldest animal names in English were not chosen by anyone we can name. They came down through the Germanic languages from Indo-European, and some were altered on the way for reasons that had nothing to do with the animal. Old English deor, our deer, meant any wild animal at all; it narrowed to the one most hunted.
Old English · Proto-Germanic
The Indo-European word for the bear survives in Latin ursus and Greek arktos. The northern languages dropped it and used a description instead, and the usual explanation is a hunters' taboo: you do not say the name of the animal you are about to meet in the woods, so you call it by its colour. English has been calling the bear the brown one ever since, and the real name never came back.
Old English · imitation of the call
Some names are not words at all, only the call written down. Old English crawe is held to imitate the bird's cry, and it has cousins in Dutch kraai and German Krähe doing the same job. Owl belongs to the same family: Old English ule comes from a root that imitates a wail, and Latin ulula is the same hoot in another language.
After the Conquest
1066 to 1500
The Norman Conquest laid a second vocabulary over the first. Some native animal words were simply replaced by French ones. Others arrived from Latin and Greek through the bestiaries, describing animals that nobody in England had seen, in two parts, like a recipe.
early 1300s · Anglo-French, from Latin and Greek
Greek skiouros is usually explained as shadow-tail, an animal that sits in the shade of its own tail. The dictionary that records the explanation also notes that it looks like a folk etymology rather than a real one. Either way, the French word pushed out the native English name, acweorna, which lasted only into Middle English as aquerne and then vanished.
about 1400 · Old French, from Latin
A spine-hog. Dutch stekelvarken and German Stachelschwein build the same word from the same two parts. English took two centuries to settle the spelling, passing through porkepyn, porkpen and porpoynt on the way, and Shakespeare's ghost in Hamlet still has the older form when he threatens to make each hair stand on end like quills upon the fretful porpentine.
“And each particular hair to stand on end, / Like quills upon the fretful porpentine”Shakespeare, Hamlet, act 1 scene 5
late 1300s · Latin, from Greek
Before English had giraffe, it had a two-animal description: a camel for the neck, a leopard for the spots. The constellation Camelopardalis, added to the star maps around 1590, still carries the old name. Giraffe itself comes from Arabic zarafa, arrived by way of French in spellings like jarraf and ziraph, and only settled into its modern form around 1600, when it retired the camel-leopard for good.
Greek by the yard
The 1500s
Printed natural histories reached England in the 1500s, and with them the scholars' habit of naming an animal with a Greek compound: two words, one description. The words are easy to remember and describe where the animal lives or what colour it is. They say nothing about what it is related to, which is how the mistakes got in.
1560s · Late Latin, from Greek
A river-horse, from an older Greek phrase, ho hippos potamios, the horse of the river. English already owned a worn-down version of the word, ypotame, which had come through Old French around 1300; the 1500s restored the full Greek and the French form died out. The name describes the animal's address, not its family.
1560s · Portuguese and Spanish, from Provençal
Flame-coloured. The word was assembled in Provençal and reached English through the Portuguese and Spanish sailors who saw the birds first. The dictionary adds a hedge: the form may have been pulled toward the word for a Fleming, a person from Flanders, which is how a pink bird ended up sounding like a nationality.
1570s · unknown
The first penguins were great auks, the flightless birds of Newfoundland, now extinct; the name moved to the southern birds in the 1580s after Drake's voyage. Where it came from is not settled. The Welsh reading, white head, was already on offer in 1638, when Thomas Herbert wrote of birds cal'd Pen-gwins (white-head in Welch), and the great auk did have a white patch by the eye. Others point to Latin pinguis, fat. The honest dictionary entry says unknown, and this page says the same.
Carried home in a log
1600 to 1833
For two centuries most new animal names arrived the same way. Someone asked the people who lived with the animal what it was called, wrote down what they heard, and the spelling took a generation to settle. The seven words in this stretch come from seven languages on four continents, and one of them carries a sound English cannot spell.
about 1600 · Powhatan (Virginia Algonquian)
John Smith's Map of Virginia, printed in 1612, lists the animal among the beasts of the colony and reaches for the nearest English comparison. Other writers heard rahaughcum, arocoun and racowne before the spelling settled, which is what happens when eight people transcribe a language none of them speaks.
“There is a beast they call Aroughcun, much like a badger, but useth to live on trees as Squirrels doe.”John Smith, A Map of Virginia, 1612
about 1600 · Portuguese, from Tupi
In Tupi the word was not specific. Old sources say jaguara meant any large predator, and a related form, jacare, is the alligator. Portuguese narrowed it to the spotted cat and English took the Portuguese word, so a name that once meant something dangerous now means one animal.
1690s · Malay, through Dutch
Person of the forest. Jacob Bontius, a Dutch physician in Java, printed the word in 1658 above a drawing of a hairy, upright, entirely human-looking creature, and there is evidence the Malay term was used for the ape in the seventeenth century. There is also a suspicion, recorded in the dictionary, that it originally meant forest-dwelling people and that Europeans misheard it as the animal. Malay does not use it for the ape today.
1759 · Mexican Spanish, from Nahuatl
One of the few animal names in English that kept its original sound almost intact. Nahuatl coyotl went into Spanish as coyote and into English with the same spelling, noted from the start, the dictionary says, for its howling at night. The Aztec word is still the word.
1770 · Guugu Yimithirr
Cook's Endeavour struck the reef in June 1770 and spent seven weeks under repair at the river that now carries her name. The crew saw the animal, asked the Guugu Yimithirr people what it was, and Cook wrote the answer into the log. A later story claims the word meant I don't know. It did not: in 1898 W. E. Roth recorded gang-oo-roo among the same people, and in 1974 the linguist John Haviland published fieldwork confirming gangurru as their word for a large dark kangaroo.
“The sort which is in the greatest Plenty is the Kangooroo or Kanguru, so called by the Natives; we saw a good many of them about Endeavour River, but kill'd only 3, which we found very good Eating.”James Cook, journal of the Endeavour, August 1770
1777 · Dutch, from Khoekhoe
The word begins with a sound English cannot spell: a click, written with an exclamation mark in the Khoisan languages. Georg Forster, the naturalist on Cook's second voyage, used the Dutch spelling gnoe to get it onto a page in 1777, and the g has been silent in English ever since. Wildebeest is the Dutch and Afrikaans name for the same animal.
1833 · Afrikaans
Earth-pig, because it burrows. The Dutch settlers at the Cape named the animals they met with the farm words they had brought, and vark is Middle Dutch for a small pig. The animal is not a pig; the snout is the whole resemblance. The word appeared in German in 1824 and in English nine years later.
Two names each
1758 onward
In 1758 Linnaeus gave every animal a two-word Latin name, and since then a species has had two names: the common one, which any language may invent or borrow, and the scientific one, which is fixed by rule. The rules today are the International Code of Zoological Nomenclature, and one of the things they allow is naming an animal after a person.
1998 · a scientific description
Tim Flannery and Colin Groves described the species in 1998 from a single specimen collected in 1961 in the Cyclops Mountains of New Guinea, and named it for David Attenborough. Nobody recorded a living one for sixty-two years. In 2023 an expedition working with local communities caught one on a camera trap, and the rediscovery was published in 2025. The newest name on this page belongs to an animal that was very nearly lost before it was named.
Reading the timeline
Read down the spine and the methods change with the transport. The oldest layer describes or imitates: the brown one, the bird that says its own name. The bestiary layer builds a word from two Greek parts, so a foreign animal can be pictured without being seen. The sailing layer borrows, and the borrowed word is only as accurate as the first person's hearing. The scientific layer stops describing altogether and simply assigns.
The mistakes follow the same pattern. Turkey, guinea pig and sea lion are all descriptions that were made before anyone knew what the animal was related to, and they stayed because a name only has to be shared to work. Nobody says hippopotamus expecting a horse. That, in five methods, is how animals got their names.
The site's monster name generator works the way the 1500s did, gluing two pieces with meanings into one word, and the guide to real animals that look fake opens with the last great Greek coinage, platypus, flat-foot, given by George Shaw in 1799 to an animal he suspected was a hoax.
Try it
Six names on this page are literally two animals, or an animal and a place. The generator has every part they need. Each link loads the recipe with those parts locked; reroll the empty slots and you get the creature a medieval reader pictured from the word alone.
Every animal on this timeline except the camelopard is in the animal library, under the common name the centuries settled on and the scientific one the rulebook fixed. The turkey, the penguin and the flamingo turn up in the random bird generator, where the photograph is real even when the name is not. And the camelopard, a camel and a leopard that never existed, is the same kind of paper animal as the griffin in the guide to mythical hybrid creatures, built from two real animals to describe a third.
