Ignorant of nice changes incorporated into home (8)
I believe the answer is:
nescient
'ignorant' is the definition.
('nescient' can be a synonym of 'ignorant')
'nice changes incorporated into home' is the wordplay.
'changes' indicates an anagram.
'incorporated into' is an insertion indicator.
'home' becomes 'nest' (I've seen this before).
'nice' anagrammed gives 'cien'.
'cien' inserted into 'nest' is 'NESCIENT'.
'of' is the link.
(Other definitions for nescient that I've seen before include "Unaware of" , "Ignorant" .)
