Etymology: Gelatin is, at root, a word about cold. Its ancestor is Latin "gelare," meaning "to freeze," which shares its stem with "gelu," frost. The Italians took this verb and made "gelatina," a word for jelly or gel, because a set jelly is a substance that has frozen into a trembling solid. The French then borrowed the Italian form as "gélatine," and English took it from French. The surprise is that the word's core idea is not "food" but "solidified by cold." Medieval Latin speakers would have grasped the link at once, while modern English speakers rarely hear the freezing in it. Jelly was once a product of boiling down animal parts until they set when cooled, so the name tracked a real process. The word's meaning then broadened from the kitchen to any substance with that same quivering, set-but-soft quality.
