100 taken in by enticement for money (5)
I believe the answer is:
lucre
'money' is the definition.
(lucre is a kind of money)
'100 taken in by enticement' is the wordplay.
'100' becomes 'c' (roman numeral).
'taken in by' is an insertion indicator.
'enticement' becomes 'lure' (lure is a kind of enticement).
'c' put into 'lure' is 'LUCRE'.
'for' acts as a link.
(Other definitions for lucre that I've seen before include "There's money" , "Ill-gotten riches" , "monetary gain" , "ill-gotten gains" , "Profit dishonestly obtained" .)
