In future, a magazine will take so much paper (4)
I believe the answer is:
ream
'take so much paper' is the definition.
I know that 'paper' relates to this answer. I also know that both the answer and definition are singular nouns
'in future a magazine' is the wordplay.
'in' indicates the answer is hidden within the clue.
'REAM' can be found hidden inside 'future a magazine'.
'will' is the link.
Can you help me to learn more?
(Other definitions for ream that I've seen before include "Widen (hole); quantity of paper" , "papers" , "500 sheets, perhaps" , "Lots of paper" , "Many sheets - enlarge hole" .)
