Notice from French Catholic included to entice (6)
I believe the answer is:
seduce
'to entice' is the definition.
(I've seen this before)
'notice from french catholic included' is the wordplay.
'notice' becomes 'see' (notice can mean to spot or see).
'from french' becomes 'du' (I can't justify this - if you can you should give a lot more credence to this answer).
'catholic' becomes 'C' (abbreviation as in RC for Roman Catholic).
'included' indicates putting letters inside.
'du'+'c'='duc'
'see' going around 'duc' is 'SEDUCE'.
Can you help me to learn more?
(Other definitions for seduce that I've seen before include "Persuade (someone) to act inadvisably" , "Lead astray, corrupt" , "Persuade to be false" , "mislead" , "Lure or entice into bad behaviour" .)
