Offence taken (5)
I believe the answer is:
pique
'offence taken' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pique that I've seen before include "Wound (pride); resentment" , "Resentment; hurt pride" , "Angry resentment" , "Resentment at a slight" , "Petulant anger" .)
