Rhetorical language (7)
I believe the answer is:
oratory
'rhetorical language' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for oratory that I've seen before include "Formal speech-making, could be pompous" , "Rhetoric - place of prayer" , "prayer room" , "Rhetoric - chapel" , "Rhetorical language" .)
