Questions & Answers about Pyyhin pölyn pois hyllyltä.
Why is pölyn in the -n form instead of pölyä?
Because pölyn is a total object form: you’re wiping the dust completely away (especially reinforced by pois).
- pyyhkiä pölyn (pois) = wipe the dust off / remove it (all of it)
- pyyhkiä pölyä = wipe some dust / do some dust-wiping (partial, ongoing, or indefinite amount)
In singular nouns, the total object often looks like the genitive (-n), even though functionally it’s the object.
What does pois add here? Can I leave it out?
pois means away/off, emphasizing that the dust is removed from its place.
- Pyyhin pölyn pois hyllyltä. = I wiped the dust away/off the shelf.
- Pyyhin pölyn hyllyltä. = I wiped the dust from the shelf. (Still fine; slightly less explicit about “away”.)
With many verbs of removal, pois strongly suggests a total result, which pairs naturally with pölyn (total object).

- hyllyltä = off/from the shelf (surface)
-sta/-stä is the elative case, typically used for movement :
