where the heart is (4)
I believe the answer is:
home
'where the heart is' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for home that I've seen before include "and 23: Host side" , "goal" , "domestic" , "It's where the heart is, it's said" , "It's where the heart is, they say" .)
