Old prince given area and province (7)
I believe the answer is:
alberta
'province' is the definition.
(province of Canada)
'old prince given area' is the wordplay.
I cannot really understand how this works, but
'prince' could be 'albert' (Prince Albert, husband of Queen Victoria) and 'albert' is found within the answer.
'area' could be 'a' (maths abbreviation) and 'a' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for alberta that I've seen before include "Banff province" , "Canadian province, capital Edmonton" , "Ratable (anag)" , "region of North America" , "Beat Lar up in Canada" .)
