Incubae and succubae

I learned something interesting about incubi and succubi recently. The words themselves are derived from Latin. The stem incub- means "lie above," whereas succub- means "lie below." The endings -a and -us are feminine and masculine, respectively.

So that gives us four demons to work with. The incubus is a masculine demon who lies atop his victim, whereas the incuba is his feminine counterpart. The succuba is a feminine demon who lies below her victim, whereas the succubus is her masculine counterpart.

There is so much more to explore, including nightmares, cambions, malcubi, and more. Unfortunately, I'll have to save those musings for later...
