It's where the heart is (4)
I believe the answer is:
home
'it's where the heart is' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for home that I've seen before include "Place of origin" , "It's where the heart is, it's said" , "goal" , "and 23: Host side" , "Be it ever so humble, there's no place like it" .)
