Root Explanation

**Aeon** → The word 'aeon' comes from the Greek 'aion' (αἰών), meaning an age or a long period of time. It refers to an indefinite and very long period, often used in philosophical or cosmological contexts to denote eternity or an age.

Memory Tip

Imagine a vast stretch of time, like an 'age' ('aion') that feels endless — that's what 'aeon' represents.
