Place for vision we hear (4)
I believe the answer is:
site
'place' is the definition.
(site is a kind of place)
'vision we hear' is the wordplay.
'vision' becomes 'sight' (synonyms).
'we hear' shows a homophone (sound like).
'sight' sounds like 'SITE'.
'for' is the link.
(Other definitions for site that I've seen before include "Locate - place" , "Area set aside for building" , "Locality" , "Place for building" , "Building plot" .)
