to divide something into shares and hand them out: to apportion, allot, or distribute
At its core this word is about splitting a whole into parts and assigning those parts to people. The same action runs through every use: the land of Canaan parceled out tribe by tribe, priests sorted into working divisions, food handed out person by person, even God assigning the sun, moon, and stars to the nations as objects of worship.
Two settings give the word its most memorable color. One is peaceful and orderly: dividing an inheritance, allotting territory by measured lines, sharing food fairly so that everyone gets a portion. The other is the battlefield: dividing the spoil after a victory, the winners parceling out captured goods, clothing, and treasure. These are not separate meanings so much as the same act of distribution done in different rooms, the courtroom and the camp.
A third, narrower use is simply to split a group in two, as when a people fractured into rival camps or a raiding party divided its forces to attack from more than one side. Here the focus is on the splitting itself rather than on who receives a share.
The thread tying them together is allotment: taking what is whole and dealing it out in measured parts.
