Root Explanation

Arsenous is derived from "arsenic" (from Latin "arsenicum", which comes from Greek "arsenikon", meaning yellow orpiment) and the suffix "-ous" (meaning characterized by or full of). The term "arsenous" refers to compounds containing arsenic, particularly in its trivalent state.

Memory Tip

Think of 'arsenic' as the base element, and remember that 'arsenous' describes something that is characterized by arsenic.
