Questions & Answers about По выходным мой дедушка возит внука в парк.
Why does по выходным mean on weekends?
This is a very common Russian time expression.
по + dative plural can mean on / during / every in a repeated-time sense. So:
- по выходным = on weekends / at weekends
- по утрам = in the mornings
- по вечерам = in the evenings
It usually suggests a habitual or repeated action, not just one specific weekend.
Why is it выходным and not выходные?
Because after по in this kind of time expression, Russian uses the dative plural.
The full expression is historically/grammatically connected to something like:
- по выходным дням = on weekend days
Very often дням is omitted, and выходным remains by itself.
So:
- выходные = nominative plural, the basic dictionary form for weekends / days off
- по выходным = dative plural, used in this expression
Why does дедушка end in -а if it means grandfather and is masculine?
Some masculine Russian nouns referring to males end in -а or -я. They decline like many feminine-looking nouns, but they are still grammatically masculine.
