Root Explanation

Authenticate → It is formed from "authenticus" (from Greek "authentikos", meaning genuine or real) and the suffix "-ate" (indicating to make or to cause). The word "authenticate" means to make something genuine or to verify its authenticity.

Memory Tip

Think of making something 'genuine' or 'real' — 'authenticus' means genuine, and the '-ate' means to make. This helps you remember that authenticate means to verify something as real.
