For a word having to do with secrets, "cryptography" has a surprisingly transparent etymology. The word traces back to the Greek roots kryptos, meaning "hidden," and graphein, meaning "to write." "Kryptos" - which in turn traces to the Greek verb kryptein, meaning "to hide" - is a root shared by several English words, including "crypt," "cryptic," and "encrypt." "Krypton," the name of a colorless gaseous element used especially in some fluorescent lamps and photography flashes, also comes from "kryptos." The name was chosen because the gas is rare and hard to find.
