Root Explanation

Certifiable → It is formed from "certus" (meaning certain or sure) and the suffix "-ficare" (meaning to make). The word "certifiable" means capable of being made certain or verified.

Memory Tip

Think of something that can be made 'certain' ('certus') — that's why certifiable means it can be verified.
