Root Explanation

Coetaneous → It is formed from "co-" (meaning together) and "aeternus" (from Latin, meaning eternal or age). The word "coetaneous" refers to things that exist or occur at the same time or age, hence together in time.

Memory Tip

Think of things that exist 'together' ('co-') in the same 'age' or time ('aeternus'). This helps you remember that 'coetaneous' means existing at the same time.
