Facinating woman's ingenuity at church (5)
I believe the answer is:
witch
'facinating woman's' is the definition.
I can't judge whether this defines the answer.
'ingenuity at church' is the wordplay.
'ingenuity' becomes 'wit' (I've seen this before).
'at' means one lot of letters go next to another.
'church' becomes 'ch' (common abbreviation).
'wit'+'ch'='WITCH'
Can you help me to learn more?
(Other definitions for witch that I've seen before include "Sorceress" , "... and magician" , "Female member of coven" , "charming female" , "'The Lion, the - - and the Wardrobe'" .)
