Nonarchitecture → It is formed from "non-" (meaning not) and "architecture" (from Latin "architectura", meaning the art or science of building). The word "nonarchitecture" refers to something that is not related to the art or science of building.
Think of 'non-' meaning 'not' and 'architecture' referring to the art of building — so 'nonarchitecture' means something that is not about building.
