Subtype → It is formed from "sub-" (meaning under or below) and "type" (from Greek "typos", meaning a model or impression). The word "subtype" refers to a classification that is a specific type under a broader category.
Think of something that is a specific 'type' ('typos') that is 'under' ('sub-') a larger category — that's what a subtype means.
