Etymology

The word "norm" comes directly from Latin norma, meaning "carpenter’s square" or "rule, pattern." The Latin term originally referred to a tool used for measuring right angles, symbolizing precision and standardization. Over time, it evolved metaphorically to denote societal or mathematical standards. The concept of "normal" (conforming to a norm) also derives from this root.
