In Adelaide, fervent wishes to set aside (5)
I believe the answer is:
defer
'set aside' is the definition.
(thesaurus)
'in adelaide fervent wishes' is the wordplay.
'in' indicates the answer is hidden within the clue.
'DEFER' is hidden within 'adelaide fervent wishes'.
'to' acts as a link.
(Other definitions for defer that I've seen before include "Capitulate" , "Adjourn" , "Put off to another time" , "Put off or give way" , "Yield to another's wishes" .)
