By thensignifica at that time(allora). Quindi, parafrasando la frase in questo video, diventa he should be finished at that time. Esempio: We will be in our new house by then. = We will be living in our new house at that time. (A quel punto vivrai in una nuova casa). Esempio: I will be 25 years old by then. = I am 24 years old now, but I will be 25 years old at that time. (ora ho 24 anni, ma allora ne avrò 25).
