Cryptography → It is formed from "kryptos" (meaning hidden) and "grapho" (meaning to write). The word refers to the practice of writing in a hidden or secret manner, often for the purpose of secure communication.

Memory Tip

Think of 'hidden' ('kryptos') writing ('grapho') — that's why cryptography is all about writing in a way that keeps information secret.
