Broad road lacking a place to meet (5)
I believe the answer is:
venue
'place to meet' is the definition.
(I've seen this before)
'broad road lacking a' is the wordplay.
'broad road' becomes 'avenue' (I've seen this in another clue).
'lacking' is a deletion indicator.
'avenue' with 'a' taken out is 'VENUE'.
(Other definitions for venue that I've seen before include "Something is happening here" , "Appointed place or location" , "Chosen location" , "Appointed place as for meeting" , "place to meet" .)
