Bachelor exits wide motorway (4)
I believe the answer is:
road
'motorway' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for road that I've seen before include "Way to achieving a particular outcome" , "public highway" , "Highway or byway" , "Route travelled by sea" , "See 10" .)
