uncharted

Etymology

It is formed from English un- + charted,^[2][3][4][5] from the prefix meaning "not" and the past participle of the verb chart.^[6][7] The noun chart is from Middle French charte (“card, map”), from Late Latin charta (“paper, card, map”),^[7][1] from Ancient Greek χάρτης (khártēs, “papyrus, thin sheet”).^[1]

Earliest recorded meaning

Not shown on a map or chart, of which there is no chart: 1804, in Etymonline.^[7] Merriam-Webster dates it to 1832,^[3][8] Dictionary.com to 1840–50,^[5] and the 1989 edition of the OED to 1847;^[9] the current OED's first quotation is from the Popular Science Monthly of 1895.^[6]

Semantic evolution

The word first described seas, coasts and islands not yet mapped, as in the islands found when the Siberian coast was surveyed.^[2][6] The 1989 OED noted that it had become common in recent use.^[9] It soon took a figurative sense, "unexplored, unknown", of any field not yet investigated, and the phrases uncharted territory and uncharted waters are used of a new and unfamiliar situation.^[2][8][10]

Usage notes

Uncharted should not be confused with unchartered, "not having a charter" or, figuratively, "unregulated, lawless", recorded from 1805 in Wordsworth's Ode to Duty: the phrase is uncharted territory, not unchartered territory.^{[10][6][7][5]}
