Questions & Answers about Mökissä on hiljaista, joten nukun hyvin.
Mökissä is mökki + the inessive case ending -ssä/-ssa, meaning in(side) the cottage. Finnish often marks location with cases rather than prepositions, so you typically say mökissä for in the cottage.
Both can translate as at the cottage, but they feel different:
- mökissä (in the cottage) focuses on being inside the building.
- mökillä (adessive -llä/-lla) is more like at/on the cottage property / at the cabin (as a place) and can include being outside on the yard, by the lake, etc.
So Mökissä on hiljaista strongly suggests the quietness is inside.
Finnish often uses an impersonal/existential structure where English would use a dummy subject it.
So (Siellä) on hiljaista = It’s quiet (there).
No explicit subject is needed.
