Questions & Answers about Ŝi aĉetis eksterlandan biciklon.

Why does biciklon end in -n?

Because it is the direct object of the verb aĉetis (bought).

In Esperanto, the direct object usually takes the ending -n. So:

• biciklo = a bicycle
• biciklon = a bicycle, as the thing being bought

In this sentence, she is doing the action, and the bicycle is receiving the action, so biciklon gets -n.

Why does eksterlandan also end in -n?

Because adjectives must agree with the nouns they describe.

Since biciklon is:

• singular
• adjective-compatible
• in the accusative case (-n)

the adjective must match it:

• eksterlanda biciklo = a foreign bicycle
• eksterlandan biciklon = a foreign bicycle, as the direct object

This agreement is a very important feature of Esperanto.
