Lottery winner's option (4,3)
I believe the answer is:
lump sum
'lottery winner's option' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lump sum that I've seen before include "one lot of money" , "Substantial payment" , "as pension may be part-paid?" , "chunk of bread?" , "11 [LOLLY] as single amount" .)
