Etymology: The adjective "carapacial" is a plain formation: it takes "carapace", the hard shell that covers a turtle's back, and adds the suffix "-ial", meaning "of or relating to". Its own history is therefore short, but the parts behind it are older and more winding than the word looks. "Carapace" came into English from French, where it had been borrowed from Spanish "carapacho", a word of uncertain origin that once described the shell of a tortoise or similar creature. Spanish had borrowed the same form from the medieval Spanish world, and the "-ial" ending that completes "carapacial" traces back through Latin "-ālis" to a Proto-Indo-European source, with a route through Old French and Middle English before reaching modern English.
