Root Explanation
Superfast → It is formed from "super-" (meaning above or beyond) and "fast" (from Old English "fæst", meaning firm or secure). The word "superfast" means faster than fast or exceeding normal speed.
Memory Tip
Think of something that is 'beyond' ('super-') just being 'fast' — that's why superfast means extremely fast.
