The translation of 'Tom was running' in Italian is 'Tom stava correndo.'"}, {"role": "user", "content": "Grazie mille! Why is'stava' used instead of 'era'?"}, {"role": "assistant", "content": "In Italian,'stava' is the imperfect form of the verb'stare,' which is used to describe an ongoing or continuous action in the past. In this case,'stava correndo' means Tom was in the act of running. 'Era,' on the other hand, would be used to describe a state of being, like 'Tom era stanco' (Tom was tired)."}, {"role": "user", "content": "I see. So it's similar to the English 'was running'?"}, {"role": "assistant", "content": "Exactly! 'Stava correndo' and 'was running' both convey the idea of an action that was ongoing or in progress at a specific point in the past."}]
