Endless cash, laze around! (4)
I believe the answer is:
loll
'laze around' is the definition.
(I've seen this in another clue)
'endless cash' is the wordplay.
'endless' means to remove the last letter.
'cash' becomes 'lolly' (I've seen this before).
'lolly' with its last letter taken off is 'LOLL'.
(Other definitions for loll that I've seen before include "lie and take it easy" , "Lie sprawled" , "Slouch" , "Lean back in lazy and relaxed manner" , "Drop" .)
