Etymology

Origin of evanesce

First recorded in 1815–25; from Latin ēvānēscere “to disappear, vanish”; see origin at vanish

Explanation

To evanesce is to fade slowly out of sight. When something evanesces, it disappears. Evanesce comes from a Latin term for vanishing, and that's exactly what it means. When something evanesces, it vanishes and is gone. However, this isn't a quick disappearing act; evanescing is gradual and takes a while. As you fly in a plane, the ground gradually evanesces. In a spooky movie, a ghost may slowly evanesce and fade away. A rainbow doesn't stick around for long; it eventually evanesces. Something that is prone or likely to evanesce can be called evanescent.
