Questions & Answers about Ha risposto che la batteria arrivava il giorno seguente.
Why does the sentence use il giorno seguente instead of domani?
This is a time shift for past indirect speech. If you quoted him directly, he probably said, "La batteria arriva domani" (The battery arrives tomorrow). But because the reporting verb (ha risposto) is in the past, domani has to shift to il giorno seguente (the following day) to match that past perspective.
Can I use il giorno dopo instead of il giorno seguente?
Absolutely. Both mean "the following day" or "the day after" and are completely interchangeable when shifting domani into past indirect speech.
The translation says "was arriving", which feels like a future plan in the past. Why does Italian use the imperfect tense (arrivava)?
In everyday spoken Italian, the imperfect tense is often used as a shortcut for the "future in the past." It's a casual, common way of expressing something that was planned or scheduled to happen after that past moment.
What is the strict, formal way to express that "future in the past" instead of using the imperfect arrivava?
