What is the proper pronunciation of Como estas'?
My machine-gun-talkin' Mexican buddies say "como-stas."
So, I would err on the safe side and pronounce it "lopwah." That way, if someone calls you on it you can always say, "Yeah, that's what I said, I jes said it real fast."
Idiomatic, my dear Watson.
