Amateurish pro in Yorkshire city (5)
I believe the answer is:
ripon
'yorkshire city' is the definition.
(city in Yorkshire)
'amateurish pro in' is the wordplay.
'pro in' can be anagrammed to 'RIPON'.
Though, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for ripon that I've seen before include "Yorkshire city with cathedral and racecourse" , "North Yorkshire cathedral city" , "Town in N. Yorkshire" , "Yorks cathedral" , "northern town" .)
