First attested in the 18th century, borrowed from French ogre, from Latin Orcus(“god of the underworld”), from Ancient Greek Ὄρκος(Órkos), the personified demon of oaths ( ὅρκος(hórkos, “oath”)) who inflicts punishment upon perjurers. Doublet of orc.
etymonline
ogre (n.)
"man-eating giant of fairy tales and popular legends," 1713, hogre (in a translation of a French version of the Arabian Nights), from French ogre, first used in Perrault's "Contes," 1697, and perhaps formed by him from a dialectal variant of Italian orco "demon, monster," from Latin Orcus "Hades," which is of unknown origin. In English, more literary than colloquial. The conjecture that it is from Byzantine Ogur "Hungarian" or some other version of that people's name (perhaps via confusion with the bloodthirsty Huns), lacks historical evidence. Related: Ogrish; ogreish; ogrishness; ogreishness.
