Questions & Answers about La paciento sentas doloron en la makzelo.
Because doloron is the direct object of sentas.
In Esperanto, the direct object usually takes the accusative ending -n. Here:
- La paciento = the subject
- sentas = feels
- doloron = pain, the thing being felt
So doloro becomes doloron because it is what the patient feels.
Because en can be used in two different ways:
- en + nominative = in, inside, at a location
- en + accusative (-n) = into, indicating movement toward a place
Here there is no movement. The pain is located in the jaw, so Esperanto uses:
- en la makzelo = in the jaw
If there were movement, then -n could appear, as in something like meti ion en la skatolon = put something into the box.
