Etymology
Origin of ephemera
1670–80; < Greek ephḗmera, neuter plural of ephḗmeros, taken as singular; see ephemeral
Explanation
Ephemera don't stick around for very long. You might enjoy such ephemera as sunsets and rainbows, things appearing only briefly, and so enjoyed all the more. In Latin, ephemera was a word for a fever that didn't last long. Today, ephemera is the plural form of ephemeron, which means "something impermanent or lasting only a short time." French historian Fernand Braudel referred to events as “the ephemera of history,” likening them to fireflies that light the dark for just a moment.
