nonlasting

Nonlasting is an adjective used to describe something that does not endure for a long time. It denotes a temporary, short‑lived, or ephemeral quality of an event, effect, impression, relationship, or object.

In usage, nonlasting is often employed to distinguish transient phenomena from those that are enduring or permanent. It can apply to physical items that wear away quickly, to feelings or impressions that fade, or to trends and outcomes that prove fleeting. The term is generally neutral, though it may subtly emphasize brevity or impermanence.

Etymology and form are straightforward: nonlasting is formed from the prefix non- meaning "not" and the adjective lasting. The construction is literal and commonly understood in both formal and informal English. While the word is widely usable, speakers may choose more specific synonyms such as temporary, transient, or ephemeral when a precise sense of duration or nature is desired.
