____ Moore of "Indecent Proposal" (4)
I believe the answer is:
demi
'moore of indecent proposal' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for demi that I've seen before include "Prefix for half or part" , "Half-sized" , "Half for a dime" , "-- Moore, actress" .)
