Bachelor leaves wide street (4)
I believe the answer is:
road
'street' is the definition.
(I've seen this in another clue)
'bachelor leaves wide' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'leaves' suggests deleting specific letters.
'wide' becomes 'broad' (synonyms).
'broad' with 'b' taken away is 'ROAD'.
(Other definitions for road that I've seen before include "Mine passage; way" , "mine gallery" , "Highway or byway" , "'The . . . . to hell is paved with good intentions'" , "Path" .)
