Borrowed from French carte, from Latin charta. See card, chart.
Borrowed from Latin charta, from Ancient Greek χάρτης (khártēs). Cognate with French charte.
From Latin charta (probably borrowed), from Ancient Greek χάρτης (khártēs, “papyrus, paper”).
Inherited from Latin charta, possibly through a hypothetical earlier Romanian intermediate form *cartă, and created from its plural (thus deriving its meaning from "many papers"). Ultimately from Ancient Greek χάρτης (khártēs). Doublet of cartă, a borrowing.
