In France, you study Italian (6)
I believe the answer is:
tuscan
'italian' is the definition.
(someone from Tuscany in Italy)
'in france you study' is the wordplay.
'in france you' becomes 'tu' ('you' in French).
'study' becomes 'scan' (I've seen this before).
'tu'+'scan'='TUSCAN'
(Other definitions for tuscan that I've seen before include "Person from Siena" , "Relating to a region of Italy" , "From a central Italian region" , "Classical architecture" , "European" .)
