Ephemeral is an adjective that is used to describe something that is short-lived or transitory. It is derived from the Greek word "ephemeros," which literally means "lasting only one day." The term is most commonly used to describe things that are fleeting or temporary, such as a feeling, an emotion, an event, or a phenomenon.
Ephemeral things can include a variety of different phenomena, such as a sunset, a rainbow, a shooting star, a dream, a memory, a feeling, a thought, a song, a moment, a sensation, a mood, a story, a joke, a conversation, a relationship, a season, a trend, a fashion, a movement, a fad, a friendship, a love affair, or a passion.
Ephemeral things are contrasted with permanent things, which are things that are long-lasting or permanent. Examples of permanent things include physical objects, such as buildings, monuments, and artifacts; natural phenomena, such as mountains, rivers, and oceans; and abstract concepts, such as laws, theories, and beliefs.
