Really regret returning boulangerie's bread? (5)
I believe the answer is:
euros
'boulangerie's bread?' is the definition.
I know nothing about this answer so I can't tell whether this works.
'really regret returning' is the wordplay.
'really' becomes 'so' (both can mean 'extremely').
'regret' becomes 'rue' (to rue something is to regret it).
'returning' says the letters should be written in reverse.
'so'+'rue'='sorue'
'sorue' back-to-front is 'EUROS'.
Can you help me to learn more?
(Other definitions for euros that I've seen before include "Common currency" , "currency in Greece" , "Monetary units" , "money" , "Continental currency units" .)
