[{"role": "user", "content": "I'm trying to learn Italian and I'm stuck on the sentence 'Tom's sleeping'. Can you help me translate it?"}, {"role": "assistant", "content": "Certo, I'd be happy to help you! The translation of 'Tom's sleeping' in Italian is 'Tom sta dormendo'."}, {"role": "user", "content": "That's really helpful, thanks! Why is'sta' used instead of'sta dormendo'?"}, {"role": "assistant", "content": "In Italian,'sta' is a shortened form of'sta' which is the third person singular of the verb'stare', meaning 'to be'. So 'Tom sta dormendo' literally means 'Tom is sleeping'. The'sta' is used to indicate that Tom is in the state of sleeping."}]
