Root Explanation

Superharden is formed from "super-" (meaning above or beyond) and "harden" (from Old English "hyrdan", meaning to make hard). The word means to make something harder beyond the usual level of hardness.

Memory Tip

Think of making something 'harder' ('harden') to an 'above' ('super-') level — that's what superharden means.
