Summary
The mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing.
Postal authorities often have functions aside from transporting letters. In some countries, a postal, telegraph and telephone (PTT) service oversees the postal system, in addition to telephone and telegraph systems. Some countries' postal systems allow for savings accounts and handle applications for passports.
The Universal Postal Union (UPU), established in 1874, includes 192 member countries and sets the rules for international mail exchanges as a Specialized Agency of the United Nations.
The word mail comes from the Middle English word male, referring to a travelling bag or pack. It was spelled in that manner until the 17th century and is distinct from the word male. The French have a similar word, malle, for a trunk or large box, and mála is the Irish term for a bag. In the 17th century, the word mail began to appear as a reference for a bag that contained letters: "bag full of letter" (1654). Over the next hundred years the word mail began to be applied strictly to the letters themselves and the sack as the mailbag. In the 19th century, the British typically used mail to refer to letters being sent abroad (i.e. on a ship) and post to refer to letters for domestic delivery. The word Post is derived from Old French poste, which ultimately stems from the past participle of the Latin verb ponere 'to lay down or place'. So in the U.K., the Royal Mail delivers the post, whilst in North America both the U.S. Postal Service and Canada Post deliver the mail.
The term email, short for "electronic mail", first appeared in the 1970s.
