More about "Envelop" and "Envelope"

The verb "to envelop" (without an "e" on the end) means "to surround" or "to enclose." It is sometimes confused with the noun "envelope," which most commonly refers to a flat rectangular paper container for a letter.

Envelop

The verb "to envelop" can mean "to surround," "to enclose," "to cover up," "to conceal," or — in military circles — "to conduct a flanking manoeuvre." In the 19th century, the verb was spelled with an "e" on the end, and this likely contributes to people confusing it with "envelope." In the past tense, the "e" reappears (e.g., The German division enveloped the town.)

Example sentences with "envelop":


"The bridge was enveloped by fog."
  • Every year, an eerie mist envelops the hotel on the anniversary of his gruesome murder.
