Get singular state flag raised (7)
I believe the answer is:
inherit
'get' is the definition.
(inheriting is a kind of getting)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for inherit that I've seen before include "Receive by succession or via a will" , "Receive as bequest from will" , "Receive from a deceased parent" , "Receive (as part of estate)" , "Come into (money)" .)
