Breaking Down Evanescent

The fragile, airy quality of evanescent things reflects the etymology of the word evanescent itself. It’s from a form of the Latin verb evanescere, which means "to evaporate" or "to vanish.” (Evanescere is also the ultimate source of vanish.) Given the similarity in spelling between the two words, you might expect evaporate to be from this family as well, but its source is another steamy Latin root, evaporare.
