Cash enticement has corrupted leader (5)
I believe the answer is:
lucre
'cash' is the definition.
(I know that lucre is a type of cash)
'enticement has corrupted leader' is the wordplay.
'enticement' becomes 'lure' (synonyms).
'has' means one lot of letters goes inside another.
'leader' says to take the initial letters.
The initial letter of 'corrupted' is 'c'.
'lure' going around 'c' is 'LUCRE'.
(Other definitions for lucre that I've seen before include "ill-gotten gain" , "ill-gotten gains" , "Ill-gotten riches" , "profits" , "Wealth - cruel (anag)" .)
