Questions & Answers about La plombaĵo estas en la dento.
In this sentence, plombaĵo means a dental filling.
It is built from:
- plomb- = the root
- -aĵ- = a suffix meaning a concrete thing, substance, or result
- -o = noun ending
So plombaĵo is the actual filling itself.
Esperanto has:
- la = the
- no separate word for a/an
So:
- la plombaĵo = the filling
- la dento = the tooth
If Esperanto leaves out la, the noun can be indefinite or general depending on context. Here, la shows that the speaker has a specific filling and a specific tooth in mind.
