[{"role": "user", "content": "I'm trying to learn some essential phrases in Italian for a trip, and I was wondering how I could politely tell someone 'You're very dirty' in Italian?"}, {"role": "assistant", "content": "The translation of 'You're very dirty' in Italian is 'Siete molto sporche.'. However, please note that this phrase can be considered quite direct. If you want to be more polite, you could say 'Sembra che sia un po' sporco' which means 'You seem to be a bit dirty'. But if you still want to use the original phrase, 'Siete molto sporche' is the correct translation."}]
