Questions & Answers about Latem biegamy pod górę w parku.
Latem is the instrumental singular form of lato (summer), used adverbially to mean in (the) summer / during summer.
Polish often uses the instrumental without a preposition to express time, especially with seasons:
- latem – in (the) summer
- zimą – in (the) winter
- wiosną – in (the) spring
- jesienią – in (the) autumn
So Latem biegamy… literally is “(In) summer, we run…” without needing w.
Yes, W lecie biegamy pod górę w parku is grammatically correct and means essentially the same thing.
Nuance:
- Latem sounds a bit more neutral and very common in everyday speech.
- W lecie also means in the summer, slightly more explicit, sometimes a bit more “spelled out,” but not wrong or strange.
Both are fine; latem is just more compact and idiomatic.
