Root Explanation

Encryption → It is formed from "en-" (meaning to cause to be) and "crypt" (from Greek "kryptos", meaning hidden or secret) and the suffix "-ion" (indicating the action or process). The word "encryption" refers to the process of causing information to be hidden or made secret.

Memory Tip

Think of the process of 'causing' something to be 'hidden' — that's what encryption means.
