Etymology

The word "aura" originates from Greek αὔρα (aúra), meaning "breeze" or "air." In ancient Greek philosophy, it described the invisible breath or vapor surrounding living beings, later evolving into the metaphysical concept of an energy field. The modern sense of "atmosphere" or "impression" emerged in the 18th century, influenced by Romanticism's focus on intangible qualities.
