Usually fromProto-Indo-European*mrogʰnom, possibly athematicized form of original*mrégʰmn̥ (whenceAncient Greekβρέχμα(brékhma,“brainpan”)), from the root*mregʰ-(“marrow, sinciput”).
Liberman instead sees this word asborrowed from a putativeProto-Celtic*bragnom,*bregnom(“bran”) (compare*bragnos(“rotten”)), deriving it fromProto-Indo-European*bʰreg-(“to break”) while proposing that it was used as a metaphor for the brain's appearance.[1]
