Seat chucked, we hear? (6)
I believe the answer is:
throne
'seat' is the definition.
(throne is a kind of seat)
'chucked we hear?' is the wordplay.
'chucked' becomes 'thrown' (I've seen this before).
'we hear?' shows a homophone (sound like).
'thrown' sounds like 'THRONE'.
(Other definitions for throne that I've seen before include "Chair of the monarch" , "Seat of monarch" , "Royalty sits on it" , "Regal seat" , "Oh rent out this seat" .)
