IPA: /ˌsʌb.kɒnˈtɪn.ənt.əl/
KK: /sʌbˈkɒntɪnəntəl/
Relating to a large landmass that is smaller than a continent, often used to describe regions like the Indian subcontinent.
The subcontinental climate varies greatly from one region to another.
Subcontinental → It is formed from "sub-" (meaning under or below) and "continent" (from Latin "continentem", meaning land or territory). The word describes a large landmass that is smaller than a continent, thus being 'under' the full size of a continent.
Think of something that is 'under' ('sub-') a larger landmass ('continent') — that's why subcontinental refers to a large area that is part of a continent but not quite a full continent.
