Fuss about French article in Spanish city (6)
I believe the answer is:
toledo
'spanish city' is the definition.
(city in Spain)
'fuss about french article' is the wordplay.
'fuss' becomes 'todo' (both can mean a commotion).
'about' indicates putting letters inside.
'french article' becomes 'le' (definite article in French).
'todo' enclosing 'le' is 'TOLEDO'.
'in' acts as a link.
(Other definitions for toledo that I've seen before include "Covering, hiding" , "Tapering sword" , "Sp. city, former Visigoth and Castilian capital" , "Sword; city in Ohio" , "Looted the Spanish city badly" .)
