Bob finally exits wide street (4)
I believe the answer is:
road
'street' is the definition.
(I know that street can be written as road)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for road that I've seen before include "Route travelled by sea" , "Way travelled by boat" , "See 10" , "Highway or byway" , "See 2" .)
