 The Serbian form has parallels in virtually all Slavic languages : Bulgarian and Macedonian вампир ( vampir ) , Bosnian : lampir , Croatian vampir , Czech and Slovak upír , Polish wąpierz , and ( perhaps East Slavic @-@ influenced ) upiór , Ukrainian упир ( upyr ) , Russian упырь ( upyr ' ) , Belarusian упыр ( upyr ) , from Old East Slavic упирь ( upir ' ) ( note that many of these languages have also borrowed forms such as " vampir / wampir " subsequently from the West ; these are distinct from the original local words for the creature ) . The exact etymology is unclear . Among the proposed proto @-@ Slavic forms are * ǫpyrь and * ǫpirь .
