Proto-Basque: *muśtu-r̄
Meaning: 1 snout, muzzle 2 corner, edge 3 goatee under the lip
Bizkaian: mustur 1, 2, (Ispaster, Oñate) mustar 3
Comments: Similar to *mutu-r̄ (q.v.), but is etymologically distinct. It fits phonologically with PEC *mHărčwV 'pus; mucus, snot': cf. the correspondence of Bsq *-śt- : PNC *-rč- in Bsq *ɦeśte (~ *ɦerce) ‘intestine’ ~ PNC *HĂrčV (~ *rHĂčV ~ *čĂrHV) ‘stomach, abomasum’ (Avar ʕorčo ), and a few other cases.
