slight pang (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
twinge
'slight pang' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for twinge that I've seen before include "Slight localised pain" , "Sharp pang" , "Sharp pain (of conscience?)" , "A slight stab of pain" , "Slight pain (of conscience?)" .)
