Etymology: "Nonchartable" is formed by adding the negative prefix "non-" to "chartable," which means able to be charted, plotted or mapped. "Chart" comes from Latin "charta," meaning a leaf of papyrus, and reached English through Old French "charte" and Middle English "carte," so a chart was originally a sheet of paper before it became a diagram of data or territory. The base word "chartable" is itself a modern formation, built from "chart" with the suffix "-able," and "nonchartable" follows the same pattern. Because "nonchartable" is a recent, technical-sounding coinage, its exact first recorded date is not something I can confirm, and it is not tied to a known inventor or event. Its meaning follows straightforwardly from its parts, and it is used mainly in mathematics, statistics and cartography, where it describes a quantity or relation that cannot be plotted on a graph.
