Considerate about profanity (11)
I believe the answer is:
desecration
'profanity' is the definition.
(thesaurus)
'considerate about' is the wordplay.
'about' is an anagram indicator.
'considerate' anagrammed gives 'DESECRATION'.
(Other definitions for desecration that I've seen before include "Violating" , "doing harm to something sacred" , "Violent disrepect" , "Violently disrespectful treatment" , "Damage of anything sacred" .)
