Sullen doctor given a flower (6)
I believe the answer is:
morose
'sullen' is the definition.
(both mean miserable)
'doctor given a flower' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'given' is a charade indicator (letters next to each other).
'a flower' becomes 'rose' (I've seen this before).
'mo'+'rose'='MOROSE'
(Other definitions for morose that I've seen before include "in gloomy mood" , "Silent, gloomy and ill-tempered" , "Sullen and ill-tempered" , "Sullen, crabby" , "Gloomy and unsociable" .)
