French and Spanish agreements on article in LA state (9)
I believe the answer is:
louisiana
'french and spanish agreements' is the definition.
I can't judge whether this defines the answer.
'article in la state' is the wordplay.
'article' becomes 'an' (English indefinite article).
'in' indicates putting letters inside.
'la' becomes 'louis' (I am not sure about this - if you are sure you should believe this answer much more).
'state' becomes 'IA'.
'louis'+'ia'='louisia'
'an' going inside 'louisia' is 'LOUISIANA'.
'on' is the link.
Can you help me to learn more?
(Other definitions for louisiana that I've seen before include "Southern United State on the Gulf of Mexico" , "American state, capital Baton Rouge" , "IOU a snail over in the US state" , "State named for French king" , "US southern state" .)
