[French, from Spanish caracol, snail, possibly from Catalan and Occitan caragol, snail (since the custom of eating snails spread from Catalonia and Occitania in the late Middle Ages); akin to regional Occitan cararolo, eggshell, nutshell, and Walloon and Picard caracole, snail, all probably ultimately of expressive origin (imitative of the sound of a hollow shell).]
