Tortured genius had suffering (9)
I believe the answer is:
anguished
'suffering' is the definition.
('anguished' can be a synonym of 'suffering')
'tortured genius had' is the wordplay.
'tortured' indicates anagramming the letters (I've seen this in other clues).
'genius'+'had'='geniushad'
'geniushad' with letters rearranged gives 'ANGUISHED'.
(Other definitions for anguished that I've seen before include "Dolorous" , "Suffering greatly" , "Distressed mentally" .)
