Breakdown of Açık pencereler odaya ferahlık katıyor.
Questions & Answers about Açık pencereler odaya ferahlık katıyor.
The verb katmak (“to add”) requires the thing receiving the addition to be in the dative case: “to add X to Y.” Here, ferahlık is being added to the room, so oda takes the dative -ya → odaya.
- oda (nominative) would be unnatural, because you’re not simply mentioning “room” but indicating direction/target.
- odayı (accusative) would make sense only if you used a different verb, for example ferahlatmak (“to freshen”), which takes a direct object: Açık pencereler odayı ferahlatıyor.
