envelop
英 [ɪn'veləp] 美 [ɪn'veləp]
vt.包封；遮盖；包围
◉Etymology
“Envelop”源自古法语“envoloper”，意为“包裹”或“包围”，由“en-”（进入）和“voloper”（包裹）组合而成。而“voloper”可能与拉丁语“volvere”（滚动、包裹）有关，后者也是“revolve”（旋转）和“involve”（涉及）的词根。这一词源表明，“envelop”从一开始就带有一种将某物完全覆盖或环绕的动态意象。到了14世纪，这个词进入英语，逐渐演变为今天的拼写和用法。

◉Usage Notes
When something envelops you, it wraps around you. The Snuggie Blanket is so popular because it envelops your body, leaving only your head uncovered. Sure, it looks dorky, but it keeps you extra warm.
You probably noticed that envelop looks just like the noun envelope, minus that last letter "e", and that's an easy way to help you remember its meaning, too. Picture what an envelope does — it seals a letter completely inside, or envelops it. Envelop can also be used in a symbolic way, to describe something that consumes or occupies your mind. If the pretty girl you just met starts to envelop your thoughts, your work will suffer because you can't concentrate. Envelop comes from the late 14c. word envolupen, meaning "be involved in."
