A sort of testament? (9)
I believe the answer is:
statement
'a sort' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'of testament?' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'testament' anagrammed gives 'STATEMENT'.
Can you help me to learn more?
(Other definitions for statement that I've seen before include "Formal declaration - financial record from bank" , "Document showing credits and debits" , "Testament about something said" , "may be taken by police" , "Record of bank balance" .)
