Melk

Okay, the word for the calcium-filled, white liquid that is produced by cows that we, especially in the Midwest, like to drink is "milk." But some people pronouce it "melk."

I don't know why they do that, and even though I've heard it quite often, I'm tempted to say that it's the "wrong" way to pronounce it and it sounds "funny", but enough people say it that way that I really shouldn't say anything about it. Except to just mention that "variation" and let the world know that I say "milk".
