Distribute everything — nothing left at the end (5)
I believe the answer is:
allot
'distribute' is the definition.
(I know that distribute can be written as allot)
'everything nothing left at the end' is the wordplay.
'everything' becomes 'all' (all things).
'nothing' becomes 'O' (O resembles 0).
'at the end' indicates one should take the final letters.
The last letter of 'left' is 't'.
'all'+'o'+'t'='ALLOT'
(Other definitions for allot that I've seen before include "Distribute, give as share" , "Designate; sounds like much" , "Give as a share, or a task to be done" , "Ration" , "Dispense or distribute" .)
