Did You Know?
The fragile, airy quality of things evanescent reflects the etymology of the word evanescent itself. It derives from a form of the Latin verb evanescere, which means "to evaporate" or "to vanish." Given the similarity in spelling between the two words, you might expect "evaporate" to come from the same Latin root, but it actually grew out of another steamy Latin root, evaporare.

Latin evanescent-, evanescens, present participle of evanescere
