[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.
