Be on target and hit residence (6,4)
I believe the answer is:
strike home
'be on target' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'hit residence' is the wordplay.
'hit' becomes 'strike' (synonyms).
'residence' becomes 'home' (home is a kind of residence).
'strike'+'home'='STRIKE HOME'
'and' is the link.
Can you help me to learn more?
(Other definitions for strike home that I've seen before include "Hit the intended target" , "Deal an effective blow" , "Have an effect" , "impact" .)
