The lady with a fine bundle of papers (5)
I believe the answer is:
sheaf
'bundle of papers' is the definition.
(I've seen this before)
'the lady with a fine' is the wordplay.
'the lady' becomes 'shea' (I am not sure about this - if you are sure you should believe this answer much more).
'with' means one lot of letters go next to another.
'a fine' becomes 'f' (abbreviation).
'shea'+'f'='SHEAF'
Can you help me to learn more?
(Other definitions for sheaf that I've seen before include "Collection of papers" , "Bundle, of grain stalks say" , "Stack, bundle" , "Reaper's bundle" , "Bundle of cereal plants" .)
