List last form of seasoning (5,4)
I believe the answer is:
table salt
'seasoning' is the definition.
(I know that table salt is a type of seasoning)
'list last form' is the wordplay.
'list' becomes 'table' (list can mean a table or chart).
'form' indicates an anagram (a different form of the same letters).
'last' with letters rearranged gives 'salt'.
'table'+'salt'='TABLE SALT'
'of' acts as a link.
(Other definitions for table salt that I've seen before include "Condiment" , "contents of cellar" , "Seasoning for meal" , "item on board" , "It adds zest to meals" .)
