South African nurses nitpick on emptying small potty (7)
I believe the answer is:
bonkers
'potty' is the definition.
(thesaurus)
'south african nurses nitpick on emptying small' is the wordplay.
I cannot really see how this works, but
'south' could be 's' (abbreviation) and 's' is found in the answer.
'on' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bonkers that I've seen before include "Cuckoo" , "Nuts" , "Barmy, crackers" , "Slang for crazy, off the wall" , "They could reproduce" .)
