'Egli' is a formal way to say 'he', but it's not commonly used in modern Italian. 'Lui' is used in informal contexts, but if you want to be more formal you can simply omit the subject pronoun and use 'Ha cominciato a cantare.'"}, {"role": "user", "content": "I see, so 'Ha cominciato a cantare' is more formal than 'Lui ha cominciato a cantare'?"}, {"role": "assistant", "content": "Yes, that's correct. 'Ha cominciato a cantare' is a more formal way to say 'He began singing', but it's worth noting that the difference is quite subtle. If you're writing a story about an Italian opera singer, 'Lui ha cominciato a cantare' is perfectly fine and more common in modern Italian."}]
