Somehow smear a lot of paper (5)
I believe the answer is:
reams
'a lot of paper' is the definition.
I can't tell whether this defines the answer.
'somehow smear' is the wordplay.
'somehow' indicates an anagram.
'smear' anagrammed gives 'REAMS'.
Can you help me to learn more?
(Other definitions for reams that I've seen before include "Scrapes the barrel" , "Large quantities (of paper?)" , "a very large amount" , "Lots of paper" , "Large quantity of written matter" .)
