Questions & Answers about Civitanoj pagas imposton.
In Esperanto, -o marks a noun, and -j marks the plural.
So:
- civitano = a citizen
- civitanoj = citizens
The ending -oj is just -o + -j.
The -n ending marks the direct object: the thing directly affected by the action.
In Civitanoj pagas imposton:
- civitanoj = the people doing the action
- pagas = pay
- imposton = the thing being paid
So imposton gets -n because it is the object of pagas.
Because civitanoj is the subject, not the object.
Esperanto usually marks:
- subject: no -n
- direct object: takes -n
So:
- Civitanoj = the ones who pay
- imposton = what they pay
If you added -n to civitanoj, it would change its grammatical role.
