Steer car? One may go on foot (6)
I believe the answer is:
oxford
'one may go on foot' is the definition.
I can't judge whether this defines the answer.
'steer car?' is the wordplay.
'steer' becomes 'ox' (a steer is a castrated ox).
'car?' becomes 'ford' (Ford is a make of car).
'ox'+'ford'='OXFORD'
Can you help me to learn more?
(Other definitions for oxford that I've seen before include "- Blue; - bags" , "English university town" , "Dark blue university?" , "Type of low-heeled shoe" , "Isis their second boat" .)
