And the rest homes primarily make an impression (4)
I believe the answer is:
etch
'make an impression' is the definition.
(to etch is to make an impression in something)
'and the rest homes primarily' is the wordplay.
'and the rest' becomes 'etc' (et cetera).
'primarily' says to take the initial letters.
The initial letter of 'homes' is 'h'.
'etc'+'h'='ETCH'
(Other definitions for etch that I've seen before include "Use acid to cut design" , "Draw on metal with acid" , "Score with acid" , "Carve into surface of something" , "Score deeply" .)
