sitzprobe
n.— «I looked at the schedule and said “What’s a sitzprobe?” and they said “don’t you know? Oh dear, you are ignorant.” It’s a German word which means sitting down and singing with the orchestra. First band-call, I would have called it.» —“Half A Mo Won’t Do For The Colonel” Sydney Morning Herald (Australia) May 19, 1988. (source: Double-Tongued Dictionary)
