A place for walk (6)
I believe the answer is:
avenue
'walk' is the definition.
(an avenue is a road or walkway)
'a place' is the wordplay.
'place' becomes 'venue' (I've seen this before).
'a'+'venue'='AVENUE'
'for' acts as a link.
(Other definitions for avenue that I've seen before include "Road lined with trees" , "Road leading to a house" , "Way of approach" , "Broad road or street, often with trees" , "Broad tree-lined road" .)
