Home schooling automatically produced knowledge (9)
I believe the answer is:
intuition
'knowledge' is the definition.
(intuition is a kind of knowledge)
'home schooling automatically' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'schooling automatically' becomes 'tuition' (both can mean teaching. I am not sure about the 'automatically' bit.).
'in'+'tuition'='INTUITION'
'produced' is the link.
Can you help me to learn more?
(Other definitions for intuition that I've seen before include "Sixth sense" , "women are known for it" , "an instinctive thing" , "Gut feeling" , "Instinctive knowledge" .)
