Ephemeralness is similar to ephemerality and means the quality of being short-lived or fleeting. It emphasizes the brief duration or temporary nature of something. It's about things that don't last and vanish quickly. Think of a mayfly, an insect that lives only for a day. This word applies to both physical and abstract things, like feelings or trends. It highlights the beauty and poignancy often found in things that don't endure.
