Universal anger about doctor giving offence (7)
I believe the answer is:
umbrage
'offence' is the definition.
(I know that offence can be written as umbrage)
'universal anger about doctor giving' is the wordplay.
'universal' becomes 'U' (film certificate).
'anger' becomes 'rage' (rage is a kind of anger).
'about' is a charade indicator (letters next to each other).
'doctor giving' becomes 'mb' (I am not sure about this - if you are sure you should believe this answer much more).
'rage' put after 'mb' is 'mbrage'.
'u'+'mbrage'='UMBRAGE'
Can you help me to learn more?
(Other definitions for umbrage that I've seen before include "Take this to be offended" , "In high dudgeon" , "The sulks" , "Indignation" , "Offence that's usually taken" .)
