Did you hear about that guy who thinks he's a superhero?

Yeah, I heard he's a bit certifiable if you ask me.

Right? I mean, how can anyone really believe that?

It’s wild! I wonder if he’s ever tried to get help.

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.
