Broad way (6)
I believe the answer is:
avenue
'broad way' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for avenue that I've seen before include "Broad road or street, often with trees" , "Wide (tree-lined) street" , "Tee-lined road" , "Wide and handsome street" , "Tree-lined approach to a house" .)
