[French enveloppe, from envelopper, to envelop, from Old French envoloper; see envelop.]
Usage Note: Some people dislike the pronunciation (ŏn′və-lōp′), arguing that it is pretentious for being pseudo-French and that it is unnecessary, since there is a perfectly acceptable Anglicized pronunciation, (ĕn′və-lōp′). But the pronunciation with (ŏn) is gaining in acceptability: in our 1992 survey, 30 percent of the Usage Panel used it exclusively, and another 9 percent used it occasionally; by 2011, 46 percent selected it as their preferred pronunciation. Both forms should be considered standard.

To be sure, in cold weather you may carry your house aloft with you, in the shape of a watch-coat; but properly speaking the thickest watch-coat is no more of a house than the unclad body; for as the soul is glued inside of its fleshly tabernacle, and cannot freely move about in it, nor even move out of it, without running great risk of perishing (like an ignorant pilgrim crossing the snowy Alps in winter); so a watch-coat is not so much of a house as it is a mere envelope, or additional skin encasing you.
