A quick blast (as I try to lift the fog to get some real writing done) about our main married (and harried) couple in Othello:
Othello as a name contains the word “hell;” Desdemona, the word “demon.”
Obvious. But maybe just happenstance. I don’t see in the OED a use of “demon” with that spelling (usually it’s “daemon”) contemporary to Shakespeare (long before, sure; long after [like today] of course).
Or maybe there’s something there.
Or maybe this grief-fog of mine needs to lift and leave me.
