Root Explanation

Oversanguine → It is formed from "over-" (meaning excessively) and "sanguine" (from Latin "sanguineus", meaning blood-red or cheerful). The word describes someone who is excessively optimistic or cheerful, as if they are overly filled with the vitality associated with blood.

Memory Tip

Think of being 'excessively' ('over-') filled with 'cheerfulness' or 'vitality' ('sanguine') — that's why oversanguine means overly optimistic.
