From Vulgar Latin *scoclus, *scoplus, from Classical Latin scopulus, from Ancient Greek σκόπελος (skópelos, “lookout place: hence peak, headland, promontory”). The Italian may have been borrowed from or influenced by a northern Italian language form such as Ligurian (cf. scogiu, schêuggio). Compare French écueil and Spanish escollo.
