After death, leave that French article in the possession of Elizabeth (8)
I believe the answer is:
bequeath
'after death leave' is the definition.
'bequeath' can be an answer for 'leave' (I've seen this before). I am not sure about the 'after death' bit.
'that french article in the possession of elizabeth' is the wordplay.
'that french' becomes 'que' (French for 'that').
'article' becomes 'a' (the indefinite article in English).
'in the' means one lot of letters goes inside another.
'possession of elizabeth' becomes 'beth' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'que'+'a'='quea'
'quea' put within 'beth' is 'BEQUEATH'.
Can you help me to learn more?
(Other definitions for bequeath that I've seen before include "Pass down" , "Endow" , "Hand down" , "Leave (estate or body)" , "Leave (property to another)" .)
