IPA: /ˌɛvəˈnɛsənt/
KK: /ˌɛvəˈnɛsənt/
Something that disappears quickly or is short-lived, like vapor.
The beauty of the sunset was evanescent, fading away within moments.
Evanescent → It is formed from "e-" (a variant of "ex-", meaning out of) and "vanescere" (meaning to vanish). The word describes something that is fleeting or vanishing quickly, as if it is disappearing out of sight.
Think of something that is 'vanishing' ('vanescere') 'out of' ('e-') sight — that's why evanescent means something that fades away quickly.
