Ephemerally → It is formed from "ephemeros" (Greek, meaning lasting only a day) and the suffix "-ally" (meaning in a manner). The word "ephemerally" describes something that exists or lasts for a very short time, akin to a day.
Think of something that lasts 'only a day' ('ephemeros') to remember that 'ephemerally' means existing for a brief moment.
