Origin & History of “bran”
English borrowed bran from Old French bran, but its ultimate source is unclear. modern French bran means ‘excrement’, and if this had always been a part of the word’s make-up it might have been possible to suggest a Celtic origin, perhaps a Gaulish *brenno- (Welsh braen and Irish brean both mean ‘manure’), but English bran appears never to have meant anything but ‘cereal husks’. It may ultimately be connected with burn.
