23. frag' net do deppert"
don't ask daft questions / fragen Sie nicht so blöd / не задавай таких глупых вопросов / لا تسأل مثل هذه الأسئلة الغبية
“Deppert” comes from Middle-High German depfen which means to stammer or to be confused. It’s been very commonly used in my hearing in Vienna, I can’t think why. Must be the onomatopoeia. Can be used sarcastically, ironically or as an exclamation of surprise. It’s not really translatable, but daft in English cometh close.
