Root Explanation

Descale → It is formed from "de-" (meaning down or away) and "scale" (from Latin "scala", meaning ladder or steps). The word "descale" means to remove the scale or buildup, often referring to the process of removing mineral deposits from a surface, as if taking steps down from a buildup.

Memory Tip

Think of 'removing' ('de-') layers or 'steps' ('scala') of buildup — that's why descale means to take away the scale.
