Assets of passing interest? (6)
I believe the answer is:
estate
'assets' is the definition.
(I've seen this in another clue)
'passing interest?' is the wordplay.
'passing' becomes 'e' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'interest?' becomes 'state' (interest is a kind of state).
'e'+'state'='ESTATE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for estate that I've seen before include "Car with big luggage area" , "The whole of one's worldly goods" , "Plantation" , "Property to be inherited" , "Scheme of new houses" .)
