Family do fine, in a way (4,2)
I believe the answer is:
kind of
'in a way' is the definition.
(thesaurus)
'family do fine' is the wordplay.
'family' becomes 'kin' ('kin' can be a synonym of 'family').
'fine' becomes 'f' (abbreviation).
'kin'+'do'+'f'='KIND OF'
(Other definitions for kind of that I've seen before include "After a fashion" , "Rather" , "Somewhat" , "Not exactly" .)
