African currency, Yankee wanting it (5)
I believe the answer is:
randy
'wanting it' is the definition.
(randy means wanting sex)
'african currency yankee' is the wordplay.
'african currency' becomes 'rand' (currency of South Africa).
'yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'rand'+'y'='RANDY'
(Other definitions for randy that I've seen before include "Eager to get into bed" , "boisterous locally" , "Lustful" , "Hot" .)
