Root Explanation

Mercurous is formed from "mercurius" (Latin for mercury, the element) and the suffix "-ous" (meaning full of or having the qualities of). The word refers to compounds containing mercury, specifically in its +1 oxidation state, thus indicating a quality related to mercury.

Memory Tip

Think of 'mercury' as the element and '-ous' meaning full of qualities — so mercurous refers to something that has the qualities of mercury.
