Sweet that is twice as good in France? (6)
I believe the answer is:
bonbon
'sweet' is the definition.
(I know that bonbon is a type of sweet)
'twice as good in france?' is the wordplay.
'twice as' becomes 'bon' (I can't explain this - if you can you should believe this answer much more).
'good in france?' becomes 'bon' ('good' in French).
'bon'+'bon'='BONBON'
'that is' acts as a link.
Can you help me to learn more?
(Other definitions for bonbon that I've seen before include "Candy, doubly good in France?" , "a tasty sweet - in France" , "Sweetie" , "French sweet" , "Confection" .)
