Delay South American writer with daughter (7)
I believe the answer is:
suspend
'delay' is the definition.
(thesaurus)
'south american writer with daughter' is the wordplay.
'south american' becomes 'sus' (I've seen this in other clues).
'writer with' becomes 'pen' (I've seen this in other clues).
'daughter' becomes 'd'.
'sus'+'pen'+'d'='SUSPEND'
(Other definitions for suspend that I've seen before include "Sends up (anag)" , "Stay" , "Hang - discontinue" , "Hang, defer" , "Hold up or dangle" .)
