Downright, altogether (7)
I believe the answer is:
utterly
I believe this clue is a double definition.
'downright' is the first definition.
(I've seen this before)
'altogether' is the second definition.
(synonyms)
(Other definitions for utterly that I've seen before include "Downright" , "Completely and totally" , "Completely and without qualification" , "In all respects" , "Absolutely and completely" .)
