Reportedly celebrate providence (4)
I believe the answer is:
fate
'providence' is the definition.
(thesaurus)
'reportedly celebrate' is the wordplay.
'reportedly' shows a homophone (sound like).
'celebrate' becomes 'fete' ('fete' can be a synonym of 'celebrate').
'fete' is a homophone of 'FATE'.
(Other definitions for fate that I've seen before include "Lot -- doom" , "Lady luck" , "Final issue" , "One's lot" , "What must be" .)
