crocodile
/ˈkrɒk.ə.daɪl/·noun·c. 1275 CE in Middle English as 'cocodrille'; modern 'crocodile' spelling established by mid-16th century·Established
Origin
From Greek krokodilos — probably meaning 'pebble-worm' for the animal's rough skin — borrowed into Latin as crocodilus, corrupted through medieval manuscripts into 'cocodrille' and even the mythical 'cockatrice', before settling into English by the 14th century; its most lasting legacy may be the phrase 'crocodile tears', kept alive by an ancient falsehood.
Definition
A large, carnivorous, semi-aquatic reptile of the order Crocodilia, characterised by a long snout, armoured skin, and powerful jaws, native to tropical regions of Africa, Asia, the Americas, and Australia.
The Full Story
Latin via GreekClassical to Late Medievalwell-attested
TheEnglish word 'crocodile' enters the language in the 14th century, borrowed from Latin 'crocodilus', which itself is a Latinisation of Ancient Greek 'krokodilos' (κροκόδειλος). The Greek word is attested from the 5th century BCE, most famously in Herodotus (Histories, Book II, c. 440 BCE), who used it to describe the Nile crocodile encountered by Greeks in Egypt
Did you know?
Theword 'crocodile' and the word 'cockatrice' — the fire-breathing heraldic serpent of medieval legend — are the same word, split by time and misreading. Medieval scribes copying Latin 'cocodrillus' conflated it with 'calcatrix' (a treader or trampler), and the resulting hybrid 'cocatrix' detached entirely from the Nile reptile and attached itself to an imaginarymonster. By the timescholars reconnected the original Greek to the actual animal, the cockatrice had already entered heraldry, scripture
'pebble' or 'gravel', and 'drilos' (δρῖλος), meaning 'worm' or 'lizard'. The literal sense is therefore 'pebble worm' or 'gravel lizard' — a vivid descriptive coinage for a large, rough-
reptile. Some scholars, including Robert Beekes, have argued that 'krokodilos' may be a non-Greek substrate word, possibly of pre-Greek or Egyptian origin adapted into Greek phonology, though the folk-etymological compound analysis is widely accepted. In Latin, 'crocodilus' appears in Caesar and Pliny the Elder (Natural History, c. 77 CE). Medieval Latin sometimes rendered it 'cocodrillus', giving rise to Old French 'cocodrille' and Middle English forms. The Modern English spelling 'crocodile' was stabilised by the 16th century, influenced by the classical Latin form. The word is etymologically isolated compared to core Indo-European fauna vocabulary. Key roots: kroke (κρόκη) (Ancient Greek: "pebble, gravel, rough stone — describing the stony riverbank or the animal's textured skin"), drilos (δρῖλος) (Ancient Greek: "worm, earthworm; extended to lizard-like creatures"), *ker- (Proto-Indo-European: "hard, rough surface — a speculative upstream connection to Greek kroke, though the link is not firmly established").
