Orcs are big goblins who can fight
This brings up an important question actually. The word “orc” has a diverse etymology. Just skimming the Wikipedia page:
The lexicography has been complicated by the Bosworth-Toller dictionary’s conjecture that orcneas devolved from the form *orcen possibly meaning “(?) a sea-monster,” possibly related to Icelandic: orkn (örkn).
So it would seem that historically the name “orc” relates to more of a demonic or giant-like/ogre-like creature, or maybe even an aquatic one. As far as I can tell, Tolkien was the first to use the word to describe a goblinoid.
In World of Warcraft, the other “big influencer” when it comes to contemporary orcs, they trace their lineage back to a stone giant called Grond, calling back to the Latin and 1656 Oxford English Dictionary interpretations.
So my question is… how popular is the idea that orcs are goblinoids really?
