Root Explanation

Decipher is formed from "de-" (meaning down from or away) and "cifra" (from Old French, meaning a zero or a cipher). The word means to decode or interpret something that is obscured or difficult to understand, essentially taking something away from its coded form.

Memory Tip

Think of 'taking away' ('de-') the 'code' ('cifra') to understand what it means. This helps you remember that to decipher is to decode or make sense of something hidden.
