Accept later you're a chip off the old block (4,5)
I believe the answer is:
take after
'you're a chip off the old block' is the definition.
I can't judge whether this defines the answer.
'accept later' is the wordplay.
'accept' becomes 'take' (to accept is to take possession of).
'later' becomes 'after' (I've seen this before).
'take'+'after'='TAKE AFTER'
Can you help me to learn more?
(Other definitions for take after that I've seen before include "the next scene in the film" , "Resemble as child often does parent" , "Favour" , "Resemble (an elder relative)" , "Look or be like, say parent" .)
