Suffering evident in unit, or men triumphant? (7)
I believe the answer is:
torment
'suffering' is the definition.
(I know that torment is a type of suffering)
'in unit or men triumphant?' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TORMENT' can be found hidden inside 'unit or men triumphant'.
'evident' acts as a link.
(Other definitions for torment that I've seen before include "Harry" , "Severe pain" , "Hound" , "Physical or mental pain" , "Extreme mental or physical distress" .)
