Raise money on a piece of ivory? (4)
I believe the answer is:
pawn
'raise money' is the definition.
(thesaurus)
'on a piece of ivory?' is the wordplay.
'on' means one lot of letters go next to another.
'a piece' becomes 'paw' (paw is a kind of piece).
'of ivory?' becomes 'n' (I am not sure about this - if you are sure you should believe this answer much more).
'paw' put next to 'n' is 'PAWN'.
Can you help me to learn more?
(Other definitions for pawn that I've seen before include "Deposit as security for a loan" , "Man of lowest value" , "Put into hock" , "Part with temporarily to raise money" , "To pop, hock" .)
