The translation of 'Did Tom say why' in Italian is 'Ha Tom detto il perch\u00e9?' or in a more informal way 'Tom ha detto il perch\u00e9?'"}, {"role": "user", "content": "Grazie! So what is the difference between 'Ha Tom detto il perch\u00e9?' and 'Tom ha detto il perch\u00e9?'?"}, {"role": "assistant", "content": "In Italian, the word order can be flexible, but it changes the emphasis. 'Ha Tom detto il perch\u00e9?' is a more formal or emphatic way of asking, where 'Ha' is stressed. 'Tom ha detto il perch\u00e9?' is a more informal way and it's the word order that you would use in a normal conversation with friends."}, {"role": "user", "content": "I see, so I can use 'Tom ha detto il perch\u00e9?' with my friends, but 'Ha Tom detto il perch\u00e9?' is more formal. What about in writing? Should I use the formal or informal version?"}, {"role": "assistant", "content": "In writing, it's generally better to use the formal version 'Ha Tom detto il perch\u00e9?' unless you're writing to someone you're very close to or in an informal setting like a text message or social media post."}]
