Orator (7)
I believe the answer is:
speaker
'orator' is the definition.
(I know that orator can be written as speaker)
This is all the clue.
(Other definitions for speaker that I've seen before include "One in pulpit, say" , "Parliamentary presiding officer" , "Orator" , "He asks for order" , "Leader of the majority party in US House of Representatives" .)
