Allot, with "out" (4)
I believe the answer is:
mete
'allot with out' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mete that I've seen before include "boundary" , "Dole (out)" , "To - out is to dispense (eg, justice)" , "Dish (out)" , "Apportion" .)
