The fellow's English, settling in European country as one granted concession (10)
I believe the answer is:
franchisee
'one granted concession' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'the fellow's english settling in european country' is the wordplay.
'the fellow's' becomes 'his' (belonging to a man).
'english' becomes 'E' (abbreviation).
'settling in' means one lot of letters goes inside another.
'european country' becomes 'France' (country in Europe).
'his'+'e'='hise'
'hise' inserted inside 'france' is 'FRANCHISEE'.
'as' is the link.
Can you help me to learn more?
(Other definitions for franchisee that I've seen before include "businessman" , "One granted retail rights" , "Person running business" , "person with property rights" , "one granted a special concession" .)
