Enticement including cold cash (5)
I believe the answer is:
lucre
'cash' is the definition.
(I've seen this before)
'enticement including cold' is the wordplay.
'enticement' becomes 'lure' (lure is a kind of enticement).
'including' is an insertion indicator.
'cold' becomes 'c' (eg on taps).
'lure' placed around 'c' is 'LUCRE'.
(Other definitions for lucre that I've seen before include "Criminal gains maybe" , "profits" , "ill-gotten gains" , "Possession of the rich" , "tin" .)
