Exchange or use money abroad (5)
I believe the answer is:
euros
'money abroad' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'exchange or use' is the wordplay.
'exchange' indicates anagramming the letters.
'or'+'use'='oruse'
'oruse' with letters rearranged gives 'EUROS'.
Can you help me to learn more?
(Other definitions for euros that I've seen before include "Rouse (anag.)" , "Continental currency units" , "money" , "Monetary units" , "Common currency" .)
