Woman with a folio bundle (5)
I believe the answer is:
sheaf
'bundle' is the definition.
(I know that bundle can be written as sheaf)
'woman with a folio' is the wordplay.
'woman' becomes 'shea' ().
'with' means one lot of letters go next to another.
'a folio' becomes 'f' (publishing abbreviation).
'shea'+'f'='SHEAF'
(Other definitions for sheaf that I've seen before include "Bundle of wheat" , "Tied bundle (of corn)" , "Bundle of cereal plants" , "Bundle, of grain stalks say" , "Collection of papers" .)
