Bovine cross in English city (6)
I believe the answer is:
oxford
'english city' is the definition.
(I've seen this before)
'bovine cross' is the wordplay.
'bovine' becomes 'ox' (ox is a kind of bovine).
'cross' becomes 'ford' (to ford a river is to cross it).
'ox'+'ford'='OXFORD'
'in' acts as a link.
(Other definitions for oxford that I've seen before include "City on the Thames" , "Isis their second boat" , "University city" , "Dark blue university?" , "Famous 16" .)
