Home, sibling before time — make it a requirement (6)
I believe the answer is:
insist
'make it a requirement' is the definition.
I can't tell whether this definition defines the answer.
'home sibling before time' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'sibling' becomes 'sis' (short for sister).
'before' means one lot of letters go next to another.
'time' becomes 't' (abbreviation).
'in'+'sis'+'t'='INSIST'
Can you help me to learn more?
(Other definitions for insist that I've seen before include "Refuse to give way" , "Beg persistently and urgently" , "'Demand, make sure (6)'" , "Be firmly demanding" , "Put one's foot down" .)
