means A flat, foldable paper container designed to hold and protect a letter or document, typically sealed shut for sending by mail.
from From French 'enveloppe,' from the verb 'envelopper' meaning 'to wrap up, enclose, or surround' — a relative of 'develop,' which is essentially its undoing (to un-wrap). The 'en-' is the familiar 'in,' and the rest traces back through Old French to a Late Latin root of uncertain origin, possibly tied to a word for wrapping or rolling. So an envelope is, quite literally, the act of wrapping made into a thing.
