Steer, following ring road to reach city (6)
I believe the answer is:
oxford
'city' is the definition.
(Oxford is an example)
'steer following ring road' is the wordplay.
'steer' becomes 'ox' (a steer is a castrated ox).
'following' becomes 'f.' (used when citing page numbers etc).
'ring' becomes 'o' (letter resembling a ring).
'road' becomes 'rd' (abbreviation).
'ox'+'f'+'o'+'rd'='OXFORD'
'to reach' acts as a link.
(Other definitions for oxford that I've seen before include "English university on Thames" , "Ancient university town" , "- Blue; - bags" , "University city" , "University - shoe" .)
