Etymology

Origin of apportionment

First recorded in 1620–30; apportion + -ment

---

Explanation

Apportionment is deciding how to divide things up and distribute them. While the apportionment of the candy from a piñata can be chaotic, milk apportionment in a school cafeteria is much more orderly. The apportionment of tax dollars may be contentious in your town if some people object to the amount of spending that goes to the yearly fireworks display. This controversy may result in the apportionment of blame on a few specific city council members. Apportionment is also used for the number of congressional representatives each state gets, based on population: "Maine might lose a seat in the House of Representatives during the next apportionment."
