Questions & Answers about Li retiris du monbiletojn.
Because it has two different endings added to the noun stem:
- -o = noun
- -j = plural
- -n = accusative, which usually marks the direct object
So:
- monbileto = a banknote
- monbiletoj = banknotes
- monbiletojn = banknotes as the direct object
In Li retiris du monbiletojn, the banknotes are what he withdrew, so Esperanto marks them with -n.
Esperanto often marks the direct object explicitly with -n. English usually relies on word order instead.
Compare:
- Li retiris du monbiletojn. = He withdrew two banknotes.
- Du monbiletojn retiris li. = literally, Two banknotes withdrew he, but still understood as He withdrew two banknotes because -n shows what the object is.
So the -n gives Esperanto more freedom in word order.
