Questions & Answers about Peruste näkyy päätöksessä.
Näkyy is the 3rd person singular present tense of näkyä.
- näkyä = to be visible, to be seen, to appear
- näkyy = is visible / can be seen / appears
So the sentence is built around the idea that the basis/grounds are visible in the decision.
A useful contrast:
- näkyä = something is visible
- näyttää = something shows something, or looks like something
So this sentence is not saying that the basis shows the decision. It says the basis can be seen in the decision.
The ending -ssä is the inessive case, which usually means in.
So:
- päätös = decision
- päätöksessä = in the decision
This is why English uses in here, while Finnish uses a case ending instead of a separate preposition.
