Questions & Answers about Strom roste na zahradě.
- strom = tree
- roste = grows / is growing
- na = usually on, but here it is part of the natural Czech expression for location
- zahradě = garden in the locative singular form
So the sentence means The tree grows in the garden / The tree is growing in the garden.
Because na is expressing a location here, and after na Czech usually uses the locative case when talking about where something is.
The basic dictionary form is zahrada.
In the locative singular, it becomes zahradě.
So:
- zahrada = garden
- na zahradě = in/on the garden
This is one of the first big differences from English: Czech changes noun endings depending on their role in the sentence.
