Contemptuous sporting authority involved in lying (7)
I believe the answer is:
profane
'contemptuous' is the definition.
(thesaurus)
'sporting authority involved in lying' is the wordplay.
'sporting authority' becomes 'fa' (I am not sure about this - if you are sure you should believe this answer much more).
'involved in' indicates putting letters inside.
'lying' becomes 'prone' (I've seen this before).
'fa' going inside 'prone' is 'PROFANE'.
Can you help me to learn more?
(Other definitions for profane that I've seen before include "Irreverent - pagan" , "(Of language) blasphemous" , "Blasphemous, irreligious" , "Contemptuous of sacred things" , "Impious" .)
