Crocodile
The word *crocodile* traces back to ancient Greek, arriving in English through Latin after a long journey that mirrors humanity's long encounter with one of the most ancient predators still alive. The Greek form *krokodilos* — attested from the 5th century BCE — is itself a compound of uncertain but debated origin, and the animal's name has shifted in form and emphasis at nearly every stage of transmission.
Greek Origins
The earliest attested form is Greek *krokodilos* (κροκόδειλος), used by Herodotus in his *Histories* (c. 440 BCE) when describing the Nile crocodile observed during his travels in Egypt. Herodotus notes that the Ionians called the animal *krokodilos* because it resembled a lizard (*sauros*) seen basking on stone walls in their homeland. The word breaks down as *krokē* (pebble, shingle) + *drilos* (worm, or possibly lizard) — yielding something like *pebble-worm* or *gravel-lizard*, a reference to the rough, stone-like texture of the animal's skin, or perhaps to its habit of basking on pebbly riverbanks.
Some scholars dispute the *drilos* element, noting that the word for worm or lizard is phonologically unstable in early Greek. An alternative analysis suggests *deilos* (timid), but this is largely rejected. The *krokē* element is more secure.
Latin and Medieval Transmission
Latin borrowed the Greek directly as *crocodilus*, which appears in Cicero and Pliny. The Latin form is faithful to Greek, and medieval Latin writers inherited it without significant alteration. Classical Latin texts, including Pliny's *Naturalis Historia* (77 CE), describe the crocodile in considerable detail — its behaviour in the Nile, the relationship with the plover bird that cleans its teeth, its tears.
Medieval manuscripts often corrupted *crocodilus* to *cocodrillus* or *cocatrix*, the latter becoming the source of the English *cockatrice* — a mythical serpent, proof that when scholars lost sight of the actual animal, the word attached itself to monsters.
Entry into English
English acquired the word in the 14th century. The earliest recorded forms show considerable variation: *cocodrille* (c. 1340), *cokadrille*, and *crockodile*. The modern spelling stabilised through Renaissance contact with classical Latin and the print era. William Caxton's late 15th-century translations helped fix the *crocodile* form.
Old French *cocodrille* was the likely intermediary for the earliest English borrowings, itself derived from Latin *crocodilus*. The doubling of consonants and vowel shifts reflect standard sound changes through Old French.
Root Analysis
No secure Proto-Indo-European root underlies the Greek *krokodilos*. The word is most likely a pre-Greek substrate term — possibly Aegean or Anatolian — adapted by Greek speakers who encountered the animal through trade, travel, and Egyptian contact. This is consistent with a pattern in Greek where animal names (particularly exotic ones) resist PIE reconstruction.
The *krokē* element, however, does connect to Greek *krokos* (saffron, pebble) and possibly to a PIE root *\*ker-* meaning rough or hard surface, which underlies English *coarse* and *hard* through different branches. This remains speculative for the *krokodilos* compound.
Cultural Context and Semantic Shifts
In Egyptian culture, the crocodile was divine — *Sobek*, the crocodile-headed god, presided over the Nile, fertility, and military power. Greek writers knew this and treated the Nile crocodile as a quasi-sacred animal, taboo in some regions of Egypt, hunted and killed in others.
The phrase *crocodile tears* — meaning false or hypocritical grief — derives from the ancient (and false) belief that crocodiles weep while eating their prey. The belief appears in Greek sources, is repeated by Latin writers, and becomes proverbial in English by the 16th century. Sir John Mandeville's *Travels* (c. 1357) gives one of the most elaborate medieval accounts.
Cognates and Relatives
The word has no true genetic cognates — it is a borrowing, not a descendant. But its transmission has generated interesting relatives:
- Cockatrice (English): from *cocodrille* via a misreading or blending with *calcatrix* (treader), it became a fire-breathing heraldic beast - Cocodrilo (Spanish), crocodile (French), Krokodil (German): all from Latin *crocodilus* - Gharial, alligator: unrelated words for related animals — *alligator* from Spanish *el lagarto* (the lizard), ultimately from Latin *lacertus*
Modern Usage vs Original Meaning
The modern English word is taxonomically precise — *Crocodilia* as an order, with crocodiles, alligators, gharials, and caimans as families. The ancient Greek *krokodilos*, by contrast, could refer to any large reptile, and Herodotus used it as a general term for what Egyptians encountered in the Nile. The specificity came later.
The original sensory description — rough-skinned, pebble-like — has been entirely lost from common usage. We do not think of texture when we say *crocodile*. We think of the animal, then the bag, then the tears.
