Questions & Answers about Gdy pada deszcz, biorę taksówkę, a taksówkarz pomaga mi z walizką.
Here gdy means when.
In this sentence, gdy pada deszcz = when it rains.
For many everyday situations, gdy and kiedy can both mean when:
- Gdy pada deszcz...
- Kiedy pada deszcz...
Both are natural.
A rough difference is that gdy can sound a little more written or formal in some contexts, while kiedy is very common in speech. In a simple sentence like this, either one works.
Polish does not need a dummy subject like English it.
English says:
- It is raining
- It rains
But Polish simply says:
- Pada deszcz = literally something like falls rain
The verb padać is commonly used for weather phenomena:
- Pada deszcz = it’s raining / it rains
- Pada śnieg = it’s snowing / snow is falling
So there is no separate word for English it here.
