Allot, attribute (6)
I believe the answer is:
assign
I believe this is a double definition.
'allot' is the first definition.
(I know that allot can be written as assign)
'attribute' is the second definition.
(I know that attribute can be written as assign)
(Other definitions for assign that I've seen before include "Transfer or appoint to" , "Allocate (a task or duty)" , "(Of a job) allocate to someone" , "grant" , "Set aside for a specific purpose" .)
