小知识
An envelope is something that envelops, or wraps around. It usually refers to the thing you stick a stamp on and snail mail.
In the early 1700s, envelope, the noun for “wrapper,” evolved from the French enveloppe, meaning “to envelop.” Envelope is always a noun, unlike the verb envelop which means “to wrap, cloak.” Synonyms for envelope range from casing and enclosure to pouch and sheath. Virginia Woolf said, “Life is a luminous halo, a semi-transparent envelope surrounding us from the beginning.” She ditched hers by walking into a river with her pockets full of rocks.
