I read some of 1,001 Nights to Madge a while ago, maybe 43 nights' worth. Tonight I ran across one of its pesky words again, in a different context, and I realized that I never really learned how to pronounce it correctly. I finally looked it up; of course I couldn't get a single, easy answer.
From Turkish and Persian the word is derivin'
and yet there's no harm in faux-southern-style, "DIE-ven."
Yet you might assay mid-Atlantic elan
and try to pronounce it "di-VAN" or "di-VAHN."
And though I researched it, I'll still be a slouch.
I'll just say Couch.
