Questions & Answers about Ni ŝanĝas la aranĝon de la ĉambro.
The -n marks the direct object in Esperanto.
In this sentence:
- Ni = we
- ŝanĝas = change / are changing
- la aranĝon = the arrangement / layout
So aranĝon is the thing being changed, which is why it takes -n.
The basic pattern is:
- subject: who does the action
- verb: the action
- object: what receives the action
Here, we are doing the changing, and the arrangement is what gets changed.
Because ĉambro is not the direct object here.
The direct object is la aranĝon.
The phrase de la ĉambro means of the room and just tells us which arrangement we mean: the room’s arrangement/layout.
So:
- la aranĝon = direct object → takes -n
- de la ĉambro = prepositional phrase with de → no accusative -n
In Esperanto, nouns after a preposition usually do not take -n unless there is some special reason.
