But here's the thing. You can't go on national TV and pronounce the word "wunderkind" as Wonder-Kined. That's an incorrect pronunciation at every almost every syllabic opportunity. You can't do that!
It is a German word, and it has maintained its Germanic pronunciation, for the most part. Please see here. There's even an audio sample, so you can hear where you went wrong. Let's tighten that verbiage up for next time around, OK?
