Can you help me translate it?"}, {"role": "assistant", "content": "The translation of 'Did they have it?' in Italian is 'Loro la avevano?'. Don't worry if it seems tricky, Italian verb conjugations can be challenging, but you're making great progress!"}, {"role": "user", "content": "Grazie! That's really helpful. I was also wondering, what's the difference between 'loro' and 'essi'? I know they both mean 'they', but when do I use each?"}, {"role": "assistant", "content": "'Loro' and 'essi' both translate to 'they', but 'loro' is more commonly used as an object pronoun, whereas 'essi' is used as a subject pronoun. For example, 'Essi hanno' means 'They have', while 'Loro la avevano' (as we discussed earlier) uses 'loro' as an object pronoun. 'Essi' is more formal, so it's often used in writing or formal situations."}]
