bulz

Etymology
Possibly a substratum word, akin to Albanian. Numerous other theories exist, none of which are satisfactory: a link to Russian, Polish ; or from a Vulgar Latin *bulgius, from Latin (cf. French , Italian ); or a Vulgar Latin *balteum; or *bullidus, from  (as with  from ); or Albanian *buljëzë; or a Gepid *bultia. It may be derived from a German word (cf. Spanish ) through a Slavic intermediary, cf. Russian. It is more likely an internal derivation from, itself of Slavic origin or an expressive creation, through a form *bulh, bulg with plural bulgi that was remade into a singular.
