Gag about South African guy’s perfect shot? (7)
I believe the answer is:
retouch
'african guy's perfect shot?' is the definition.
I can't judge whether this defines the answer.
'gag about south' is the wordplay.
'gag' becomes 'retch' (I've seen this in other clues).
'about' indicates putting letters inside.
'south' becomes 'ou' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'retch' going around 'ou' is 'RETOUCH'.
Can you help me to learn more?
(Other definitions for retouch that I've seen before include "Make slight improvements to (a photo/picture)" , "Repair a painting" , "Fine-tune" , "Correct painting" , "Improve a photo, with a pencil say" .)
