Dramatic sort of whisper! (5)
I believe the answer is:
stage
I believe this clue is a double definition.
'dramatic' is the first definition.
(thesaurus)
'sort of whisper' is the second definition.
(Other definitions for stage that I've seen before include "Platform for actors" , "horse-drawn vehicle" , "Elevated platform" , "Acting platform; coach" , "Acting area" .)
