The translation of 'He quit smoking' in Italian is 'Ha smesso di fumare.' If you want to get a better understanding of the sentence, 'Ha smesso' means 'he quit' and 'di fumare' means'smoking'. So, the whole sentence 'Ha smesso di fumare' literally means 'he quit smoking'."}, {"role": "user", "content": "That's really helpful, thank you! Is there a more formal or informal way of saying 'he quit smoking' in Italian?"}, {"role": "assistant", "content": "The translation 'Ha smesso di fumare' is a neutral one. If you want to use a more informal tone, you can say 'Ha smesso di fumare' as well, because it's not too formal. However, if you want to use a more formal tone, you can say 'Lui ha smesso di fumare'. The word 'Lui' emphasizes 'he'."}]
