Loss of interest from years on a course (6)
I believe the answer is:
apathy
'loss of interest' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'years on a course' is the wordplay.
'years' becomes 'y' (abbreviation).
'on' says to put letters next to each other.
'course' becomes 'path' (path can mean a route or course).
'a'+'path'='apath'
'y' after 'apath' is 'APATHY'.
'from' is the link.
Can you help me to learn more?
(Other definitions for apathy that I've seen before include "Absense of interest or emotion" , "Lack of emotion and interest" , "Lack of excitement" , "Detachment" , "Unconcern" .)
