Delight about South Africa's turnaround (8)
I believe the answer is:
reversal
'turnaround' is the definition.
(synonyms)
'delight about south africa's' is the wordplay.
'delight' becomes 'revel' (I've seen this before).
'about' is an insertion indicator.
'south africa's' becomes 'rsa' (I can't justify this - if you can you should give a lot more credence to this answer).
'revel' placed around 'rsa' is 'REVERSAL'.
Can you help me to learn more?
(Other definitions for reversal that I've seen before include "A change to an opposite direction" , "Negation" , "misfortune!" , "Volte-face" , "Set back" .)
