the.com/orc

means A brutish, tusked humanoid monster, usually encountered in hordes and usually losing to the hero — a fantasy staple for disposable villainy.

from The word has old roots: Old English 'orcnēas' (a kind of demon or monster) appears in Beowulf, and Latin 'Orcus' named a god of the underworld and death. But the modern creature is largely Tolkien's invention — he borrowed the ancient, half-forgotten word and poured his own mythology into it, and later fantasy (and games like Warhammer and D&D) ran with the result, cementing 'orc' as shorthand for grunting, green-skinned cannon fodder.
