Questions & Answers about Zimą moja skóra jest sucha, dlatego piję więcej wody.
Zimą is the instrumental case of zima (winter).
In Polish, seasons can be used in the instrumental case to mean during that season:
- zimą = in winter
- latem = in summer
- jesienią = in autumn
- wiosną = in spring
So Zimą moja skóra jest sucha means In winter, my skin is dry.
You may also hear w zimie, which also means in winter, but zimą is a very common and natural way to say it.
Because Polish often uses the instrumental case by itself for time expressions like seasons.
So instead of saying literally in winter with a preposition, Polish can simply say:
- zimą = in winter
- rano = in the morning
- wieczorem = in the evening
This is just a normal Polish pattern. You do not need w before zimą here.
