D&D Pronunciation Guide

Whenever the word Tiefling comes up in our home game, my son says “tie-FLING“, and I’ve always said “TEAF-ling.” For me it is a little odd when I hear it pronounced tie-FLING, because I don’t think of it that way when I read Tiefling. But it is just a made-up word for a game of imagination, so it doesn’t really matter. But maybe there is an authority on “correct” pronunciations for these game terms that we could use.
