Going to go ahead and resurrect this just cause it seemed the most relevant place and I didn't want to start a new thread for it.
Been learning German over the last couple months, and I've learned that I (and probably most of the other folks on here) have been making a pretty big mispronunciation for a long time.
Pretty commonly used term: Brau. Commonly pronounced "brow" as in "eyebrow".
Problem is that the word "Brau" doesn't exist in that form in German, unless part of another word such as Brauerei (brewery) or Brauhaus (brewhouse). The "Brau" pronunciation is correct, but the actual word on its own is Bräu. And the pronunciation is really different because of that umlaut. It's pronounced "broy".
Common example: Löwenbräu being pronounced low-en-brow. When the correct pronunciation is closer to looer-ven-broy.
The other one is the boot glass. See lots of "Das Boot" on this forum and elsewhere (and in Beerfest). That means "the boat". Der Bierstiefel is the correct term.
