Definitions

1. Unable to be accurately charted or represented on a map; incapable of being assigned a specific location or geographic coordinates; not able to be plotted or traced spatially
2. Cannot be depicted or delineated on any map format; lacking a definable position or place in spatial terms; unable to be recorded or visualized as a geographic entity

Etymology: "Unmappable" is a plain formation: the prefix "un-", meaning "not", attached to "mappable," which itself comes from "map" with the suffix "-able," meaning "capable of being." Together they describe something that cannot be charted, plotted, or fixed to a geographic location. The base word "map" traces back to Medieval Latin "mappa," meaning a cloth or napkin, which is also the source of "mop." Early maps were sometimes drawn on cloth, so the sense of a flat sheet carrying a picture of the land grew naturally from the older meaning. The "-able" suffix comes through Old French from Latin "-abilis," and English has long used it to form adjectives from verbs, as in "readable" or "washable."
