Questions & Answers about La paciento uzas ne nur dentofadenon, sed ankaŭ buŝakvon.
Because they are the direct objects of uzas (uses).
In Esperanto, the direct object usually takes the ending -n. So:
- La paciento uzas dentofadenon. = The patient uses dental floss.
- La paciento uzas buŝakvon. = The patient uses mouthwash.
Both things are being used, so both get -n.
La means the.
So la paciento means the patient, referring to a specific patient. Without la, paciento would mean a patient or just patient in a more general sense.
Esperanto uses la for definiteness, much like English uses the.
