Silence present helpers largely set aside (6)
I believe the answer is:
shelve
'set aside' is the definition.
(I've seen this in another clue)
'silence present helpers largely' is the wordplay.
'silence' becomes 'sh' ('sh' is said to tell someone to be silent).
'present helpers largely' becomes 'elve' (I can't explain this - if you can you should believe this answer much more).
'sh'+'elve'='SHELVE'
Can you help me to learn more?
(Other definitions for shelve that I've seen before include "Postpone" , "Put on one 1 down" , "Put aside for the present, plan or book" , "Store" , "Place on a horizontal surface" .)
