IPA: //ˈmeɪn.lænd//
KK: /ˈmeɪnˌlænd/
The largest part of a continent, not including any islands nearby.
The mainland is home to most of the country's population.
Mainland → It is formed from "main" (from Old English *mǣne*, meaning principal or chief) and "land" (from Old English *land*, meaning ground or territory). The word "mainland" refers to the principal landmass of a country or region, as opposed to its islands or other territories.
Think of 'main' as the principal part and 'land' as the ground or territory — together, they describe the main area of land.
