Stereotypic → It is formed from "stereo-" (from Greek "stereos", meaning solid or three-dimensional) and "typic" (from Greek "typos", meaning model or impression). The word "stereotypic" refers to something that is characterized by a fixed or conventional model, often lacking in originality.
Think of 'solid' ('stereo-') models or impressions ('typic') that don't change — that's why stereotypic describes something that follows a fixed pattern.
