Questions & Answers about По выходным мы играем в футбол на стадионе.
По выходным is a very common Russian way to say on weekends / at weekends in the sense of a repeated habit.
- по here means something like on / during / every
- выходным is the dative plural form of выходные (the weekend days)
So literally, it is close to on weekend-days or during weekends.
This pattern is common in Russian for repeated times:
- по утрам = in the mornings
- по вечерам = in the evenings
- по понедельникам = on Mondays
- по выходным = on weekends
Because weekends are understood as a recurring set of days, not a single moment.
The base word here is выходные:
- singular adjective: выходной = day off / free day
- plural: выходные = the weekend / days off
In the phrase по выходным, Russian uses the plural because it refers to weekends in general, as a repeated time frame.
