Dear all, I apologize if my question is trivial but I couldn’t find a way out of myself.
In Familia Romana capitulum XIV pensum A, you can find the prompt:
Medicus caput dol_ sanāre nōn potest.
The teacher’s answer key suggests dolēns but I though it should be dolentem as it refers to caput which is the object of the sentence and therefore should be accusative and not nominative.
