Word Origin & History

"ogre, devouring monster," O.E. orcþyrs, orcneas (pl.), perhaps from a Romanic source akin to ogre, and ult. from L. Orcus "Hell," a word of unknown origin. Revived by J.R.R. Tolkien (1892-1973) as the name of a brutal race in Middle Earth.
"But Orcs and Trolls spoke as they would, without love of words or things; and their language was actually more degraded and filthy than I have shown it." ["Return of the King," 1955]
