Fools include their first belongings (6)
I believe the answer is:
assets
'belongings' is the definition.
The definition and answer can be both related to property as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'fools include their first' is the wordplay.
'fools' becomes 'asses' (ass is a kind of fool).
'include' is an insertion indicator.
'their first' becomes 't' (1st letter of 'their').
'asses' enclosing 't' is 'ASSETS'.
Can you help me to learn more?
(Other definitions for assets that I've seen before include "capital" , "Advantages" , "Useful or valuable possessions or qualities" , "property worth having" , "Useful skills" .)
