Etymology: "Reptiles" is simply the plural of "reptile," so the story belongs to its singular. The root is Latin "rēpere," "to creep," which descends from an ancient reconstructed root meaning the same thing. The Latin adjective "reptilis" meant "creeping," and its neuter form "reptile" was used as a noun for a creeping thing, a sense that carried into Late Latin. The word reached English through Old French, arriving in Middle English as "reptil." Its meaning has stayed close to the literal image of crawling. Early uses covered any low creature that moved along the ground, and only later did the sense narrow to the scaly, cold-blooded group we now know, from snakes and lizards to turtles and crocodiles.

Synonyms: cold-blooded animals
