Assistant on course to stop working under disreputable man (6)
I believe the answer is:
caddie
'assistant on course' is the definition.
'caddie' can be an answer for 'assistant' (caddie is a kind of assistant). I'm not sure about the 'on course' bit.
'stop working under disreputable man' is the wordplay.
'stop working' becomes 'die' (I've seen this in other clues).
'under' means one lot of letters go next to another.
'disreputable man' becomes 'cad' (I have seen 'Dishonourable man ' mean 'cad' so perhaps 'man' could also mean 'cad'. I am not sure about the 'disreputable' bit.).
'die' put after 'cad' is 'CADDIE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for caddie that I've seen before include "assist on course?" , "Golfer's aide" , "Wages advice note" , "A golfer's assistant-adviser" , "Golfer's assistant on course" .)
