I like
Demeter, but I'm still not sure how to say it. I've heard various ways so often (I'm pagan so I suppose I hear it more than most people) and each person seems convinced they've got it right. I say "de-MEE-ter", but a lot of my friends say "DEH-meh-ter".
But regardless, I like that one best, it seems most straightforward and I like the non-a ending actually.
