It ties into place (4)
I believe the answer is:
site
'place' is the definition.
(I know that place can be written as site)
'it ties' is the wordplay.
'ties' can be anagrammed to 'SITE'.
Though, I'm not sure how this is indicated.
'into' is the link.
Can you help me to learn more?
(Other definitions for site that I've seen before include "Locality" , "Where something is located" , "Somewhere to build, perhaps" , "Area set aside for building" , "Ties into building location" .)
