Ephemeras are items that are meant to be used or enjoyed for a short time. There are several synonyms for this word, including transients, temporary items, fleeting objects, and short-lived artifacts. Other words that can be used to describe ephemeras include impermanent, momentary, evanescent, and passing. Ephemeral items are often used in the context of art, such as in performance or installation art, where the temporary nature of the piece is an essential part of its meaning. Regardless of the context, ephemeras are something to be appreciated while they last, never to be taken for granted, and quickly forgotten once they are gone.
