Root Explanation

Anodize → It is formed from "anode" (from Greek "anodos", meaning way up or ascent) and the suffix "-ize" (meaning to make or to become). The word "anodize" means to make a surface (usually metal) into an anode, which is a positively charged electrode in electrolysis, thus creating a protective oxide layer.

Memory Tip

Think of 'anode' as a way to 'ascend' or 'go up' in the process of creating a protective layer on metal, which is what anodizing does.
