Are left in it to guard her (7)
I believe the answer is:
inherit
'are left in it to guard her' is the definition.
I can't judge whether this definition defines the answer.
'in it to guard her' is the wordplay.
'to guard' means one lot of letters goes inside another.
'in'+'it'='init'
'init' going around 'her' is 'INHERIT'.
Can you help me to learn more?
(Other definitions for inherit that I've seen before include "Receive as bequest from will" , "Be the recipient of" , "Receive from a predecessor" , "Be left with (a situation)" , "Get what was left?" .)
