Utterly depressed? True (9)
I believe the answer is:
downright
'utterly' is the definition.
(thesaurus)
'depressed? true' is the wordplay.
'depressed?' becomes 'down' ('down' can be a synonym of 'depressed').
'true' becomes 'right' ('right' is associated in meaning with 'true').
'down'+'right'='DOWNRIGHT'
(Other definitions for downright that I've seen before include "True" , "Completely" , "Out-and-out" , "Plain-spoken" , "blunt" .)
