"Envelop" (no final E) = to wrap or surround completely; "envelope" (with final E) = the paper container for letters.
Verb: to wrap, surround, or cover completely from all sides. Used for fog, flames, darkness, warmth, or anything that surrounds something. "The fog enveloped the city." Pronounced en-VEL-op.
A thick blanket of fog enveloped the harbor, making navigation nearly impossible.
The warmth of the fireplace seemed to envelop everyone in the room with a sense of comfort.
Flames enveloped the entire third floor before firefighters could reach the building.
Noun: the paper or material container used to send a letter or document by mail. "Seal the envelope." Pronounced EN-vuh-lope or AHN-vuh-lope.
She sealed the envelope with a damp sponge and pressed down the flap carefully.
He found a cream-colored envelope slipped under his office door with no return address.

Common mistake
Classic error: "Please put the letter in the envelop" (should be "envelope" with E). Or writing "the darkness envelope the room" (should be "enveloped" — verb form, no final E). The final E distinguishes the noun (envelope) from the verb (envelop). Different pronunciation: the noun can stress the first syllable (EN-ve-lope); the verb stresses the second (en-VEL-op).
Trick to remember it
EnvelopE (noun, with E) = the E at the end helps you remember it is an Envelope, the physical object. EnveloP (verb, no final E) = you use it to wrap something. Pronunciation trick: the VERB envelop stresses the second syllable: en-VEL-op. The NOUN envelope stresses the first: EN-ve-lope. If you hear the accent shift, you can tell which one is being used.
Quick rule
Envelop (no final E) = verb, to wrap or surround (the fog enveloped...). Envelope (final E) = noun, a mail container (seal the envelope).
