Root Explanation
Coeval → It is formed from "co-" (meaning together) and "aevum" (meaning age or era). The word describes things that exist or occur during the same time period or age.
Memory Tip
Think of things that exist 'together' ('co-') in the same 'age' ('aevum') — that's why coeval means contemporary or of the same age.
