Current business representative left his wounded master at specialist to show proficiency (14)
I believe the answer is:
accomplishment
'show proficiency' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'current business representative left his wounded master at specialist' is the wordplay.
'current' becomes 'ac' (alternating current).
'business representative left his wounded' becomes 'complish' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'master' becomes 'm'.
'at' is a charade indicator (letters next to each other).
'specialist' becomes 'ent' (Ear, Nose and Throat specialist).
'ac'+'complish'+'m'+'ent'='ACCOMPLISHMENT'
'to' is the link.
Can you help me to learn more?
(Other definitions for accomplishment that I've seen before include "Something achieved" , "exploit" , "Successful achievement" , "Skill" .)
