Took a seat for a conversation piece (3)
I believe the answer is:
sat
'took a seat' is the definition.
(I've seen this before)
'for a conversation piece' is the wordplay.
'piece' indicates a hidden word.
'SAT' can be found hidden inside 'for conversation'.
(Other definitions for sat that I've seen before include "Was sitting" , "part of the weekend" , "Rested" , "Was in session" , "Perched" .)
