📖 Root Explanation

Derived from Latin 'aeternus', meaning 'lasting', from 'aevum' meaning 'age' or 'eternity'. The root conveys the idea of unending duration.

💡 Mnemonic

Think of 'eternal' as 'e-ter-nal': 'e' for endless, 'ter' sounds like 'forever', and 'nal' reminds you of 'final' but with no end. So, eternal means never final and always lasting.

📖 Example

My best friend and I made a promise of eternal friendship when we were kids. 🔊 During our childhood, my best friend and I pledged a friendship that would never end.
