Comments:KW 323, Poppe 29 (Mong.-Tung.), Лексика 412, Whitman 1985, 188, 234 (Kor.-Jpn.). In Turkic -lm- reflects *-ĺm- ("Helimski's rule"). *-j- has to be reconstructed to account for the loss of -ĺ- in Kor. This is the only root pertaining to metal terminology that can be reconstructed for PA, and it is not quite clear what metal was meant (perhaps meteorite iron - it is highly dubious that the speakers of PA possessed any kind of developed metallurgy). Note that in the Turko-Mong. area the metal name as such was lost and preserved only within the name of iron objects (sabre, armour).
