Beelzebub m (genitive Beelzebubes or Beelzebubs or Beelzebub, plural Beelzebube)
Translating Ancient Greek Βεελζεβούλ (Beelzeboúl) and Hebrew בעל זבוב (ba‘al-z'būb, “fly-lord”); perhaps a corruption of Beelzebul, meaning Lord of the High Place, with -bul altered to -bub to change the meaning to Lord of the Flies.
(Classical) IPA(key): /beˈel.ze.bub/, [bɛˈɛɫ.zɛ.bʊb]
Beelzebub m (indeclinable)
