Offend a female head (7)
I believe the answer is:
affront
'offend' is the definition.
(affronting is a kind of offending)
'a female head' is the wordplay.
'a female' becomes 'af' (I've seen this in other clues).
'head' becomes 'front' (I've seen this in other clues).
'af'+'front'='AFFRONT'
(Other definitions for affront that I've seen before include "Cause of outrage or offence" , "Deliberate insult or show of disrespect" , "Snub" , "Insult openly" , "provocation" .)
