Blasphemy making girl cease playing (9)
I believe the answer is:
sacrilege
'blasphemy' is the definition.
(synonyms)
'girl cease playing' is the wordplay.
'playing' is an anagram indicator.
'girl'+'cease'='girlcease'
'girlcease' is an anagram of 'SACRILEGE'.
'making' acts as a link.
(Other definitions for sacrilege that I've seen before include "Extreme disrespect for something holy" , "Impious act" , "Blasphemy" , "profanity" , "Disrespect or damage to something sacred" .)
