Start game when golf is banned (5)
I believe the answer is:
rouse
'start' is the definition.
'game when golf is banned' is the wordplay.
I cannot quite see how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
The remaining letters 'rous' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rouse that I've seen before include "Prod" , "Stir into action" , "Cause to wake up and come alert" , "Stir up; excite" , "To start" .)
