Possibly list the weight of cheese (7)
I believe the answer is:
stilton
'cheese' is the definition.
(stilton is a cheese)
'possibly list the weight' is the wordplay.
'possibly' is an anagram indicator.
'the weight' becomes 'ton' (unit of weight).
'list' with letters rearranged gives 'stil'.
'stil'+'ton'='STILTON'
'of' is the link.
(Other definitions for stilton that I've seen before include "Type of cheese" , "Cheese named after Cambridgeshire town" , "Blue 8 across" , "Rich, blue-veined cheese" , "Cheese variety" .)
