Cultivated a desire for cash (7)
I believe the answer is:
readies
'cash' is the definition.
(I've seen this before)
'cultivated a desire' is the wordplay.
'cultivated' indicates an anagram.
'a'+'desire'='adesire'
'adesire' anagrammed gives 'READIES'.
'for' acts as a link.
(Other definitions for readies that I've seen before include "money" , "Cash -- a desire (anag)" , "Bank notes" , "The - - : cash (sl.)" .)
