Comments:Meithei nam-gal ~ nam-gan, Kham kàl kidney; Chepang kal. Sh. 47; Ben. 18. Some forms reflect *kjVɫ - apparently a merger with *gjV̆nH 'kidney' q.v.: cf. Taraon kɨ.3 jɨŋ.1, Tani *ki, Rengma agen, Tiddim gil 'belly', Magar mi-gin 'heart'.
Comments:It is possible that *kāɫ 'pole, club', *kān (~-ɫ) 'knock' and *kāɫ 'barrier, shield' actually represent one and the same original root ('wooden block, cudgel or shield'). Cf. also designations for 'penis' in Kham (or-kal) and Garo gol-teŋ, see STEDT 328-329 *ga[l/r] 'penis'. Cf. *kār.
