[{"role": "user", "content": "I'm trying to learn Italian and I'm stuck on the sentence 'They heard it'. Can you help me translate it?"}, {"role": "assistant", "content": "The translation of 'They heard it' in Italian is 'L'hanno sentito'. However, a more common and grammatically correct way to say it would be 'Loro l'hanno sentito'. But if you want to use a more formal way, you can say 'Lo hanno sentito loro'. But if you want to emphasize 'it', then 'Loro l'hanno sentito' is the correct way to say it."}]
