gluten (English)
Where does "gluten" come from?
The English noun 'gluten' was borrowed from Middle French 'gluten', which itself derives directly from the Latin word 'glūten', meaning 'glue'[1]. Going back further, the Latin noun developed from Proto-Italic '*gloiten' and ultimately traces to the Proto-Indo-European root '*gleh₁y-', which meant 'to stick' or 'to spread, to smear'[2]. While the word historically referred to gluey, sticky substances or bodily humors, in modern usage it specifically designates the elastic protein substance found in cereal grains like wheat.
