Kind of home abroad (2,1,3)
I believe the answer is:
in a way
Here is my best explanation:
'kind of' is the definition.
'home abroad' is the subsidiary indication.
'home' becomes 'in' ('he's home' can mean 'he's in').
'abroad' becomes 'away' (I've seen this before).
(Other definitions for in a way that I've seen before include "To a limited extent, in some respects", "from one point of view", "To a certain extent", "Kind of", "somehow", "From some points of view", "In some respects, to a limited extent", "To some degree", "Sort of, to a limited extent" and "Sort of, in some respects".)
