What does 'A lui' mean and why is it used here?"}, {"role": "assistant", "content": "'A lui' is a pronoun that means 'to him' or 'him'. In this sentence, it's used to indicate that the headache is affecting him. It's a way to express that the action of the verb is happening to the subject, rather than the subject performing the action."}, {"role": "user", "content": "I see, so it's like saying 'it was happening to him'?"}, {"role": "assistant", "content": "Exactly! That's a good way to think about it. And then 'faceva male' is the verb phrase that means 'was hurting' or 'ached', and 'la testa' means 'the head'. So when you put it all together, 'A lui faceva male la testa' is a common way to say 'he had a headache'."}]
