[{"role": "user", "content": "I'm trying to learn Italian and I came across the sentence 'I had never seen it.' Can you help me translate it into Italian so I can better understand how to express this idea in the language?"}, {"role": "assistant", "content": "The translation of 'I had never seen it' in Italian is 'Io non lo avevo mai visto.' This sentence is in the passato procomposto tense, which is used to describe an action that occurred before another action in the past."}, {"role": "user", "content": "That's really helpful, thank you! So, how would I use 'Io non lo avevo mai visto' in a sentence to express that I had never seen something before?"}, {"role": "assistant", "content": "You can use 'Io non lo avevo mai visto' in a sentence like this: 'Quando ho incontrato mio cugino, io non lo avevo mai visto prima.' This means 'When I met my cousin, I had never seen him before.' It's a great way to express the idea that you had no prior experience or encounter with something or someone."}]
