Course in medicine brings understanding (10)
I believe the answer is:
empathetic
'understanding' is the definition.
(I've seen this before)
'course in medicine' is the wordplay.
'course' becomes 'path' (path can mean a route or course).
'in' is an insertion indicator.
'medicine' becomes 'emetic' (emetic is a kind of medicine).
'path' inserted into 'emetic' is 'EMPATHETIC'.
'brings' is the link.
(Other definitions for empathetic that I've seen before include "Understanding" , "Appreciating another's feelings" .)
