Other forms: enveloped, enveloping, envelops
To envelop is to wrap something up completely. Fog does it to a town, and arms do it to a person.
The completeness is essential, since something enveloped is surrounded on every side. It suits fog, smoke, darkness and flame, all of which arrive from outside and close in. There is a warm use about embraces. Note the spelling and stress, since the verb envelop has no e at the end and the noun envelope does, and the two are pronounced quite differently.
1verbenvelopTo wrap up or surround something completely.
“Mist will envelop the whole valley by evening.”
Also accepted in games: engulf
Envelop is wrapping in. Old French envoluper joined en, in, to voloper, to wrap, and the envelope is the same word turned into a noun.
