Ephemeral" It means 'which is in danger of speedy disappearance."
The term "ephemeral" refers to things that are transient or fleeting, emphasizing their tendency to vanish quickly. This concept is beautifully illustrated in "The Little Prince" by Antoine de Saint-Exupéry, where the impermanence of life and beauty is a central theme. The reminder that certain experiences and emotions are short-lived encourages readers to appreciate the present moment and the fragility of existence.
