[Origin: 1725–35; (< F) < G Vampir < Serbo-Croatian vàmpīr, alter. of earlier upir (by confusion with doublets such as vȁzdūh, ȕzdūh air (< Slavic vŭ-), and with intrusive nasal, as in dùbrava, dumbrȁva grove); akin to Czech upír, Pol upiór, ORuss upyrĭ, upirĭ, (Russ upýrʾ) < Slavic *u-pirĭ or *ǫ-pirĭ, prob. a deverbal compound with *per- fly, rush (literal meaning variously interpreted)]
1734, from Fr. vampire or Ger. Vampir (1732, in an account of Hungarian vampires), from Hung. vampir, from O.C.S. opiri (cf. Serb. vampir, Bulg. vapir, Ukrainian uper), said by Slavic linguist Franc Miklošič to be ult. from Kazan Tatar ubyr "witch." An Eastern European creature popularized in Eng. by late 19c. gothic novels, however there are scattered Eng. accounts of night-walking, blood-gorged, plague-spreading undead corpses from as far back as 1196. Applied 1774 by Fr. biologist Buffon to a species of South American blood-sucking bat.
