Broad road not originally a meeting place (5)
I believe the answer is:
venue
'a meeting place' is the definition.
(place for a meeting)
'broad road not originally' is the wordplay.
'broad road' becomes 'avenue' (I've seen this before).
'not originally' means to remove the first letter (the origin of the word is removed).
'avenue' with its first letter taken off is 'VENUE'.
(Other definitions for venue that I've seen before include "locale" , "Rendezvous" , "Event location" , "Appointed place as for meeting" , "Location of meeting" .)
