Proto-Korean: *kór(čhí)
Meaning: brain, marrow
Russian meaning: мозг
Modern Korean: kol
Middle Korean: kor, kór-čhí
Comments: Nam 51, KED 156. The meaning 'head' in modern dialects proves that the original meaning was 'brain, head' (in literary Korean the word usually means 'marrow' while 'brain' is expressed as mǝri-k:ol, lit. "head brain"). The meaning 'marrow' may have been additionally induced by the analogy with kol-su (MKor. kor-sju) 'bone marrow', borrowed from MC 骨髓 kot-sjwé; but Kor. *kor itself has of course nothing to do with MC kot 'bone'.
