Stereotypical → It is formed from "stereotype" (from Greek "stereos", meaning solid or firm, and "typos", meaning impression or model) and the suffix "-ical" (meaning pertaining to). The word "stereotypical" refers to something that pertains to a fixed or oversimplified model or impression.
Think of a 'solid impression' ('stereotype') that is 'pertaining to' ('-ical') a certain type — that's why stereotypical describes something that fits a fixed model.
