Taffeta bedspread was taken back to bury the argument (6)
I believe the answer is:
debate
'the argument' is the definition.
('debate' can be a synonym of 'argument')
'taffeta bedspread was taken back to bury' is the wordplay.
'to bury' indicates a hidden word.
'taken back' is a reversal indicator.
'etabed' can be found hidden inside 'taffeta bedspread was'.
'etabed' written backwards gives 'DEBATE'.
(Other definitions for debate that I've seen before include "A public discussion about a topic" , "Discuss with opposing arguments" , "Talk" , "Public discussion, perhaps a contest" , "Argue the toss" .)
