Could this be Wembley Way? (6)
I believe the answer is:
avenue
'way?' is the definition.
(I know that Avenue is a type of Road)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for avenue that I've seen before include "Entrance passage" , "Wide street or path to progress" , "Broad road or street, often with trees" , "Double row of trees" , "A broad thoroughfare as in New York" .)
