Generations refer to the successive groups of people born and living at about the same time, often distinguished by a shared attitude or common values. The term 'generations' can be broken down into two parts: EON (3 letters) and ERAS (4 letters). An EON is an indefinite and very long period of time, while an era is a period of time marked by significant events or particular characteristics. Together, these two terms represent the concept of generations, which is the passing of time and the changes that occur within it.
