The translation of 'I can't pay you' in Italian is 'Io non posso pagarvi'. If you want to be more informal, you can say 'Non posso pagarti'. 'Io non posso pagarvi' is more formal, so it would be used when speaking to someone you don't know well, or to show respect."}, {"role": "user", "content": "That's really helpful, thank you! Can you explain what the difference is between 'Io non posso pagarvi' and 'Non posso pagarti'?"}, {"role": "assistant", "content": "In Italian, 'Io non posso pagarvi' uses the formal 'you' (voi or lei), which is used when speaking to someone you don't know well, or to show respect.
