IPA: /ˌriːəˈpɔːrʧənmənt/
KK: /riːəˈpɔːrʧənmənt/
The process of redistributing seats or representation in a legislative body, often based on population changes from the census.
The reapportionment of congressional seats occurs every ten years after the census is conducted.
Reapportionment is formed from "re-" (meaning again) and "apportion" (from Old French *apportioner*, meaning to divide or distribute). The word refers to the act of redistributing or dividing something again, often in the context of political representation or resources.
Think of 'again' ('re-') and 'dividing' ('apportion') to remember that reapportionment means to divide or distribute something again.
