ümbrikule

Ümbrikule is a term of Estonian origin that translates to "envelope" in English. It refers to a folded piece of paper or cardstock used to enclose a letter, document, or other item for mailing or delivery. Envelopes typically have a flap that can be sealed, often with adhesive. They come in a wide variety of sizes, shapes, and materials, depending on their intended use. Common uses include sending personal correspondence, business documents, invitations, and promotional materials. Historically, envelopes were made from parchment or vellum, but modern envelopes are almost exclusively made from paper. The design and function of the envelope have remained relatively consistent over centuries, serving as a fundamental tool for communication and the secure transport of information. The term ümbrikule specifically refers to the object itself, rather than the act of enclosing something within it.
