Definition of the word eternity

The word "eternity" has its roots in ancient Greek and Latin. In Greek, the word "aion" (αιών) means "age" or "period of time," and was often used to describe the eternal nature of the gods or the universe. The Latin translation of "aion" is "aeternus," meaning "eternal" or "everlasting." The concept of eternity is thought to have originated in ancient religious and philosophical traditions, where it was often associated with the divine, the infinite, or the ultimate reality. In Western philosophy, the concept of eternity was later developed by Christian theologians, who used it to describe God's existence outside of time and space. The word "eternity" has since been used in various contexts, including spirituality, philosophy, and literature, to convey a sense of timelessness, infinity, and the ultimate.
