Small amount in France held back by virtuoso (3)
I believe the answer is:
sou
'small amount' is the definition.
(a small amount of money)
'held back by virtuoso' is the wordplay.
'back by' says the letters should be written backwards.
'held' says the answer is hidden in the clue.
'uos' can be found hidden inside 'virtuoso'.
'uos' back-to-front is 'SOU'.
'in france' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for sou that I've seen before include "bit of money" , "almost worthless" , "Defunct French coin" , "Very small amount of money" , "Former French coin of low value" .)
