Questions & Answers about Через неделю мне исполнится двадцать лет.
Через неделю means “in a week / a week from now” (counting forward from the present).
Literally, через can mean “through” or “across”, but with time it means “after, in (a certain amount of time)”.
Grammar:
- через
- accusative case = “in / after (a period of time)”
- через час – in an hour
- через месяц – in a month
- через неделю – in a week
- accusative case = “in / after (a period of time)”
So неделю is accusative singular of неделя (“week”), required by the preposition через.
