Somewhat directionless anger (3)
I believe the answer is:
ire
'anger' is the definition.
(ire is intense rage)
'somewhat directionless' is the wordplay.
'somewhat' indicates a hidden word.
'IRE' is hidden in the letters of 'directionless'.
(Other definitions for ire that I've seen before include "Anger, rage" , "passion" , "resentment" , "Losing head" , "Irritation, anger" .)
