'ephemerality' originates from Greek, specifically the word 'ephemeros,' where 'epi-' meant 'upon' and 'hemera' meant 'day.'

'ephemeros' transformed into the Late Latin word 'ephemeralis,' and eventually became the modern English word 'ephemeral' through Middle English.

Initially, it meant 'lasting only a day,' but over time it evolved into its current meaning of 'short-lived or transient.'
