Money from a priest (7)
I believe the answer is:
piastre
'money' is the definition.
(I've seen this before)
'from a priest' is the wordplay.
'from' indicates an anagram (the anagram comes from the same letters).
'a'+'priest'='apriest'
'apriest' with letters rearranged gives 'PIASTRE'.
(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" .)
