Hurt someone's feelings (6)
I believe the answer is:
offend
'hurt someone's feelings' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for offend that I've seen before include "Affront - break the law" , "disgust" , "tread on someone's toes?" , "Insult - act criminally" , "Violate the law" .)
