Definitions

1. Devoid of clearly established paths or navigational aids, existing in a realm that is difficult to navigate due to uncertainty, and marked by a significant lack of direction or guidance in unfamiliar situations
2. Having no maps or charts to guide navigation, making locations or routes unknown
3. Describes a place or area without cartographic representation, thus hard to find or plot

Etymology: "Chartless" is a plain formation: the noun "chart" (a map, especially one made for sailors) with the suffix "-less," meaning "without." A chartless sea or coastline is one that has never been mapped, so a navigator sails into it without any guide to its shoals, islands, or depths. The word has a close relative in "cardless," which follows the same pattern but uses "card" in its older sense of a navigational chart, a meaning that comes from the same source as the playing card's ancestry in the idea of a sheet of paper or board. The two words are doublets in the loose sense that they are built from parallel pieces that carry much the same meaning, one drawn from "chart" and the other from "card." Their shared logic is what makes the pair worth noticing: English reached the same idea of an unmapped, unguided place twice, through two different nouns for a map.

Synonyms: directionless, aimless, unmapped, indeterminate, uncharted
