transience

This term evokes a sense of fragility and the inevitable passage of time. It is frequently employed in philosophical, poetic, or spiritual contexts to describe the fleeting nature of human existence, beauty, or emotion, often carrying a melancholic or reflective tone. As an uncountable noun, it describes an abstract quality or state of being. It does not have a plural form and cannot be counted with numbers; instead, it is referred to as a concept or a characteristic of a specific period or object.
