Questions & Answers about Po deszczu często wychodzi słońce.
Because po in the sense of after is followed by the locative case in Polish.
- deszcz = rain
- po deszczu = after the rain / after rain
So deszcz changes to deszczu because of the preposition po.
A useful pattern is:
- po obiedzie = after dinner
- po pracy = after work
- po filmie = after the film
In this sentence, po deszczu is a fixed, very natural way to say after rain or after the rain.
It is the locative singular.
The dictionary form is deszcz. After po meaning after, Polish uses the locative:
- nominative: deszcz
- locative: deszczu
For this noun, the locative form happens to end in -u.
Polish does not have articles like the or a/an.
So:
- słońce can mean the sun or just sun
- deszcz can mean the rain or just rain
The exact meaning depends on context. In this sentence, English naturally uses the sun, but Polish simply says słońce.
