Learned about cold anger and outrage (9)
I believe the answer is:
sacrilege
'outrage' is the definition.
(thesaurus)
'learned about cold anger' is the wordplay.
I cannot quite see how this works, but
'about' could be 'c' (abbreviation for circa) and 'c' is located in the answer.
'anger' could be 'rile' (I've seen this in another clue) and 'rile' is found in the answer.
'learned' could be 'sage' (both can mean wise) and 'sage' is present in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for sacrilege that I've seen before include "Extreme disrespect for something holy" , "Misuse of something sacred" , "Blasphemy" , "Violation of something sacred" , "Violation of a holy thing" .)
