Tempt French nobleman in bishop's domain (6)
I believe the answer is:
seduce
'tempt' is the definition.
(I know that seduce is a more specific form of tempt)
'french nobleman in bishop's domain' is the wordplay.
'french nobleman' becomes 'duc' ('duke' in French).
'in' means one lot of letters goes inside another.
'bishop's domain' becomes 'see' (I've seen this before).
'duc' inserted into 'see' is 'SEDUCE'.
(Other definitions for seduce that I've seen before include "get into bed?" , "Charm - deprave" , "Lure or entice away from proper behaviour" , "mislead" , "Perhaps do this to pull" .)
