Questions & Answers about La pedalo turnas la ĉenon.
In Esperanto, -o is the noun ending.
So:
- pedalo = pedal
- ĉeno = chain
Almost all basic nouns end in -o. This makes it easy to recognize what kind of word you are looking at.
Notice that ĉenon still has the noun ending -o; it just also has an extra -n after it for another grammatical reason.
The -n marks the direct object of the verb — the thing being acted on.
In La pedalo turnas la ĉenon:
- la pedalo = the pedal → the thing doing the action
- la ĉenon = the chain → the thing being turned
So ĉenon has -n because the chain is receiving the action.
This is called the accusative ending.
