Pirates roving for money overseas (7)
I believe the answer is:
piastre
'money overseas' is the definition.
I can't tell whether this defines the answer.
'pirates roving' is the wordplay.
'roving' indicates anagramming the letters.
'pirates' with letters rearranged gives 'PIASTRE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for piastre that I've seen before include "bit of money" , "Syrian money" , "Former coin in some Middle Eastern countries" , "Foreign currency" , "Small amount of money" .)
