Writing material daily (5)
I believe the answer is:
paper
I believe this is a double definition.
'writing material' is the first definition.
(I've seen this in another clue)
'daily' is the second definition.
(newspaper)
(Other definitions for paper that I've seen before include "Treatise" , "Set of examination questions" , "See 10/25/18/20" , "Daily publication" , "Scholarly article" .)
