Made sore by rubbing (6)
I believe the answer is:
chafed
'made sore by rubbing' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for chafed that I've seen before include "Made sore from rubbing" , "Became sore from rubbing" , "Irritated by rubbing" , "Rubbed" , "Abraded by rubbing" .)
