nine-point

The compound "nine-point" is a transparent Modern English formation, combining the cardinal number "nine" with the noun "point." The word "nine" descends from the Proto-Indo-European root h₁néwn̥, a stable numerical term that evolved directly into the Old English nigon. "Point" has a more vivid history, originating from the Latin punctum, meaning a small hole or mark made by piercing. This literal sense of a precise, marked location broadened over centuries to denote a unit of measurement, a detail in an argument, and a geometric location. Thus, "nine-point" logically denotes a system, figure, or scale characterized by nine such distinct units or positions, maintaining a direct link between its compositional morphemes and its modern descriptive function.

Structure: nine (number) + point (location/unit) - nine: From Old English nigon, of Germanic origin; related to Dutch negen and German neun, from an Indo-European root shared by Latin novem and Greek ennea. Functions as a cardinal number. - point: From Old French point, from Latin punctum ‘something that is pricked’, giving rise to senses like ‘unit, mark, location’. Functions as a noun indicating a precise spot, detail, or unit of measurement.
