Limited object the French authorise (7)
I believe the answer is:
entitle
'authorise' is the definition.
(I know that entitle is a more specific form of authorise)
'limited object the french' is the wordplay.
'limited' means to remove the last letter (a limited or incomplete form of the word).
'object' becomes 'end' (both can mean a goal or purpose).
'the french' becomes 'title' (I can't explain this - if you can you should give a lot more credence to this answer).
'end' with its final letter taken away is 'en'.
'en'+'title'='ENTITLE'
Can you help me to learn more?
(Other definitions for entitle that I've seen before include "Name; empower" , "Allow" , "term" , "Give one the right - name" , "Style; give right to" .)
