Etymology

from Middle English cocodrille "crocodile," from early French cocodrille (same meaning), from Latin cocodrillus and earlier crocodilus "crocodile," from Greek krokodeilos "crocodile, lizard"

Word Origin

The word crocodile is taken from Greek krokodeilos, which is probably modified from a compound of krokē, "pebble, stone," and an obscure word drilos, which may have meant "worm." According to the ancient Greek writer Herodotus, some Greeks gave this name to the lizards that lived among the stone walls of their farms. When these Greeks visited Egypt, the enormous reptiles of the Nile River reminded them of the lizards and they applied the same name to them. (The more usual ancient Greek word for "lizard" was sauros, which we see in the Latin scientific names of many dinosaurs, such as Tyrannosaurus, and in the word dinosaur itself.) The Romans took Greek krokodeilos into Latin as crocodilus. However, later speakers shifted the r from the first to the third syllable, giving cocodrilus or cocodrillus. It was this form that was taken into medieval French and later into Middle English as cocodrille. Later, as Englishmen became better acquainted with the classical Latin of ancient Rome, the English word was changed to better reflect Latin crocodilus, and cocodrille was eventually forgotten.
