Ephemeral
adjective /ɪˈfemərəl/ — Things that last only a short time.
Definition
Lasting for a very short time; fleeting by nature.
Beyond the definition
Used to describe beauty, moments, or feelings that are precious because they won't stay. The ephemeral quality of cherry blossoms is exactly why they're celebrated.
Origin & history
Ultimately from Greek ephemeros, meaning 'lasting a day,' through Latin ephemera. English ephemeral is recorded in the 1560s for things lasting one day; the broader sense 'short-lived' developed in the 1630s.

Ephemeral vs transient
Ephemeral and transient both mean short-lived or temporary. Ephemeral emphasizes brief duration, as in ephemeral fame or an ephemeral bloom; it does not necessarily mean beautiful or precious. Transient can also describe people staying somewhere temporarily. A poetic context may give ephemeral emotional weight, but that is an effect of the writing, not a fixed difference in meaning.
