Etymology: "Stereotypy" is the psychiatric and developmental term for repetitive, involuntary movements or behaviours, such as hand-flapping, rocking, or repeated phrases. The word is built from "stereotype" with the suffix "-y", which forms abstract nouns, so its core sense is the quality or condition of being fixed and repeated. The root "stereotype" has a printing origin. It comes from the Greek "stereos", meaning solid or firm, combined with "typos", meaning impression or type. A stereotype in this original sense was a solid metal plate cast from a set of movable type, allowing a page to be reprinted without resetting the letters. The idea of an unchanging, reproduced form is what carried over into the later figurative sense of a fixed, standardised image. The term "stereotypy" was borrowed into English from French "stéréotypie", which itself was formed from "stéréotype" with the same suffix. Its medical use reflects that same underlying image of a fixed pattern that repeats without variation.
