…home schooling - it makes sense! (9)
I believe the answer is:
intuition
'sense' is the definition.
(intuition can mean a sense or instinct)
'home schooling' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'schooling' becomes 'tuition' (both can mean teaching).
'in'+'tuition'='INTUITION'
'it makes' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for intuition that I've seen before include "Sixth sense" , "Unjustified belief" , "An indefinable knowledge" , "Innate understanding" , "Hunch" .)
