IPA: /ˈʌpˌsteɪtə/
KK: /ˈʌpˌsteɪtər/
A person who comes from the northern part of a state, especially New York.
My friend is an upstater who loves the mountains and lakes.
Upstater → The word is formed from "up" (meaning higher or above) and "state" (from Old French *estat*, meaning condition or position) with the suffix "-er" (meaning a person who). An upstater refers to a person from a higher or more elevated state or region, often used in the context of someone from a more rural or northern area compared to a metropolitan area.
Think of someone from a 'higher' ('up') 'condition' or 'position' ('state') — that's why an upstater is a person from a higher region.
