Devilish chap, very attractive, seen around church, note (10)
I believe the answer is:
maleficent
'devilish' is the definition.
(thesaurus)
'chap very attractive seen around church note' is the wordplay.
I cannot quite understand how this works, but
'chap' could be 'mal' and 'mal' is found within the answer.
'around' could be 'c' (abbreviation for 'circa') and 'c' is located in the answer.
'note' could be 'n' (abbreviation) and 'n' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for maleficent that I've seen before include "Harmful" , "Evil" .)
