Get parent's stuff in their devious way (7)
I believe the answer is:
inherit
'get' is the definition.
(inheriting is a kind of getting)
'parent's stuff in their devious way' is the wordplay.
'parent's stuff' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'in' is an insertion indicator.
'devious' indicates anagramming the letters.
'way' becomes 'n' (Compass direction - North).
'their' with letters rearranged gives 'herit'.
'herit' going around 'n' is 'nherit'.
'i'+'nherit'='INHERIT'
Can you help me to learn more?
(Other definitions for inherit that I've seen before include "Gain by succession" , "Acquire from ancestors" , "Succeed as heir" , "Receive as bequest from will" , "Be bequeathed" .)
