Proto-Sino-Tibetan: *kāɫ ( ~ g-, G-)
Meaning: pole, club
Tibetan: mgal, ãgal a billet of wood.
Kachin: khon2 a club, cudgel.
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.
