Questions & Answers about La riĉa homo aĉetis novan biciklon.
La is the definite article, like English the. It shows that the speaker has a specific person in mind: la riĉa homo = the rich person.
Esperanto has only one definite article, la, and it never changes form.
Esperanto normally has no indefinite article. English distinguishes a bicycle and the bicycle, but Esperanto usually just has:
- biciklo = a bicycle / bicycle
- la biciklo = the bicycle
So novan biciklon naturally means a new bicycle here.
