Surly doctor is given flower (6)
I believe the answer is:
morose
'surly' is the definition.
(thesaurus)
'doctor is given flower' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'is given' is a charade indicator (letters next to each other).
'flower' becomes 'rose' (I've seen this in other clues).
'mo'+'rose'='MOROSE'
(Other definitions for morose that I've seen before include "Peevish and gloomy" , "Glum or sour-tempered" , "Sullen. bad-tempered" , "Lugubrious" , "Sullen or glum." .)
