Probably from Italian orco (“man-eating giant”); later revived by J. R. R. Tolkien, partly after Old English orc, which he took to mean "demon". Both are from Latin Orcus (“the underworld; the god Pluto”). Doublet of ogre and Orcus. Etymology 2 sense 2 is a semantic loan from Ukrainian орк (ork, “evil monstrous humanoid creature; orc”) or Russian орк (ork), both from English orc and possibly under the influence of Russian у́рка (úrka, “criminal”, prison slang). Popularized in English in 2022, following the Russian invasion of Ukraine.
