South Africa's uncommon outing (6)
I believe the answer is:
safari
'outing' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for safari that I've seen before include "African hunting expeiditon" , "tropical trip" , "Overland journey to look for wild animals" , "[PARK] trip" , "Expedition to see animals" .)
