An orc (sometimes spelt ork; ɔrk), in J. R. R. Tolkien's Middle Earth fantasy fiction, is a race of humanoid monsters, which he also calls "goblin".
Especially in Tolkien's The Lord of the Rings, orcs appear as a brutish, aggressive, ugly, and malevolent race of monsters, contrasting with the benevolent Elves. They are a corrupted race of elves, either bred that way by Morgoth, or turned savage in that manner, according to the Silmarillion.
The orc was a sort of "hell-devil" in Old English literature, and the orc-né (pl. orc-néas, "demon-corpses") was a race of corrupted beings and descendants of Cain, alongside the elf, according to the poem Beowulf. Tolkien adopted the term orc from these old attestations, which he professed was a choice made purely for "phonetic suitability" reasons.
Tolkien's concept of orcs has been adapted into the fantasy fiction of other authors, and into games of many different genres such as Dungeons & Dragons, Magic: The Gathering, and Warcraft.
The word orc probably derives from the Latin word/name Orcus.

Orc, in Anglo-Saxon, like thyrs, means a spectre, or goblin."
In the sense of a monstrous being, the term is used just once in Beowulf, as the plural compound orcneas, one of the tribes belonging to the descendants of Cain, alongside the elves and ettins (giants) condemned by God:
The meaning of Orcneas is uncertain. Frederick Klaeber suggested it consisted of orc < L. orcus "the underworld" + neas "corpses", to which the translation "evil spirits" failed to do justice. It is generally supposed to contain an element -né, cognate to Gothic naus and Old Norse nár, both meaning 'corpse'. If *orcné is to be glossed as orcus 'corpse', then the compound word can be construed as "demon-corpses", or "corpse from Orcus (i.
