Where, in Spain, the French appear in a big fuss (6)
I believe the answer is:
toledo
'where in spain' is the definition.
The definition suggests a singular noun which matches the answer.
'the french appear in a big fuss' is the wordplay.
'the french' becomes 'le' ('the' in French).
'appear in' indicates putting letters inside.
'a big fuss' becomes 'todo' (I've seen this in another clue).
'le' placed into 'todo' is 'TOLEDO'.
Can you help me to learn more?
(Other definitions for toledo that I've seen before include "Sp. city, former Visigoth and Castilian capital" , "Blade" , "Spanish city on R. Tagus" , "Sword; city in Ohio" , "Covering, hiding" .)
