Say you’re stranded on an island with a group of people and you divide your limited food supply. The portion you each receive is your share, also called your allotment. No fighting over the coconuts!
The word allotment shows how languages intertwined through the ages. We can see the word's origins in several languages, including the Old English hlot, the Gothic hlauts, the Old High German hloz, and the Old French aloter. All referred to dividing something into groups, or “lots.” A "lot" refers to a group of things — stores refer to shipments of goods as being divided into “lots.” That idea of grouping will help you remember the meaning of allotment.
