Комментарий: Cf. also Ud. Nidzh. mungul 'besom' (possibly an archaic form, since *-n- is reconstructed in this root for PEC), Tsakh. Tsakh., Gelm. mugul' 'side (of body). The specific semantic development in Tsakh. is explained by a shift *'besom' > 'a rod in a besom' > 'rib' (cf. Tab. murglin ṭul 'rib', lit. "besom's rod").
