The money's right, furthermore (4)
I believe the answer is:
rand
'the money's' is the definition.
(I've seen this before)
'right furthermore' is the wordplay.
'right' becomes 'r' (common abbreviation).
'furthermore' becomes 'and' (I've seen this in another clue).
'r'+'and'='RAND'
(Other definitions for rand that I've seen before include "South African currency unit" , "our 1/4 Across [GOLD MEDALLIST] in 1964" , "Currency of South Africa" , "South African money" , "Monetary unit in South Africa" .)
