Crudités
"Crudités" is a French term, literally "raw things", from Middle French "crudité" (14c.) and directly from Latin "cruditatem" (nominative "cruditas"), from "crudus" "rough; not cooked, raw, bloody," from PIE "*krue-do-", from PIE "*kreue-" which meant "raw meat", and is the source of the English word "raw". According to Merriam-Webster the term appears to have been first used in 1960, from the plural of "crudité" or "rawness", itself deriving from the Latin "cruditas" for "indigestion" or "undigested food", coming in turn from "crudus" for "raw".
