Reportedly burn soothsayer (4)
I believe the answer is:
seer
'soothsayer' is the definition.
(thesaurus)
'reportedly burn' is the wordplay.
'reportedly' shows a homophone (sound like).
'burn' becomes 'sear' (I've seen this before).
'sear' sounds like 'SEER'.
(Other definitions for seer that I've seen before include "Person of vision" , "One fortelling future" , "One divines the future" , "Person with unusual powers of foresight" , "Prophet or visionary" .)
