Fuss about the French in Spanish city (6)
I believe the answer is:
toledo
'spanish city' is the definition.
(I've seen this before)
'fuss about the french' is the wordplay.
'fuss' becomes 'to do' (both can mean a commotion).
'about' indicates putting letters inside.
'the french' becomes 'le' ('the' in French).
'todo' going around 'le' is 'TOLEDO'.
'in' acts as a link.
(Other definitions for toledo that I've seen before include "Sword; city in Ohio" , "Spanish city famed for swords" , "Tapering sword" , "River Tagus city" , "Maker of 3 [[COLD STEEL]" .)
