Bench sent east (4)
I believe the answer is:
seat
'bench' is the definition.
(I've seen this before)
'sent east' is the wordplay.
'sent' indicates anagramming the letters (send can mean to excite or stimulate).
'east' is an anagram of 'SEAT'.
(Other definitions for seat that I've seen before include "MP's place in parliament" , "MP's constituency" , "Constituency; location" , "'A chair, say (4)'" , "pew?" .)
