Rubbish! Get a list! (4)
I believe the answer is:
rota
'list' is the definition.
(I know that rota is a type of roll)
'rubbish get a' is the wordplay.
'rubbish' becomes 'rot' (both can mean nonsense).
'get' means one lot of letters go next to another.
'rot'+'a'='ROTA'
(Other definitions for rota that I've seen before include "List of duties to be done, or people to do them" , "Cycle of duty" , "Work schedule" , "Duty roster" , "Ecclesiastical tribunal" .)
