Origin & History of “card”

English borrowed card from French carte, for some unknown reason changing t to d in the process. The French word (source also of English carton) came from Latin charta, which originally denoted ‘leaf of the papyrus plant’; and since papyrus leaves were used for making paper, the word in due course came to mean ‘paper’ (Latin charta also gave English chart and charter). The Latin word in turn came from Greek khártēs, which is probably of Egyptian origin.
