A letterbox is a receptacle placed outside a residential or commercial building, typically at the entrance, for the purpose of receiving and collecting mail. Also known as a mailbox or postbox, it is a small, usually rectangular container with a hinged door that allows for the insertion and retrieval of letters and other mail items. The purpose of the letterbox is to provide a secure and convenient location for the delivery and storage of mail until it is collected by the recipient.
Letterboxes can be found in various forms, including freestanding posts, built-in compartments on doors or walls, or attached to fences or gates. The design and placement of the letterbox can vary depending on regional and architectural preferences. They are typically positioned within easy reach for postal workers and offer a convenient location for individuals to receive important correspondence and packages without the need for direct contact.
In addition to private homes, letterboxes are also frequently used in office buildings, government institutions, and apartment complexes to facilitate organized mail delivery. These receptacles often bear the name or number of the recipient for efficient identification and sorting. The usage of letterboxes has remained prevalent despite advancements in digital communication, as traditional mail services continue to play a significant role in society and remain essential for the exchange of documents and physical goods.
The word "letterbox" originated in the mid-19th century and has its roots in the words "letter" and "box".
The term "letter" comes from the Old French word "lettre" which in turn derives from the Latin word "littera" meaning "a written character". "Littera" was influenced by the Greek word "grammata" which also means "letter" or "written character".
The word "box" has a Germanic origin and can be traced back to the Old English word "box" or "buxa" which referred to a container or receptacle.
Therefore, when combined, "letterbox" refers to a container or receptacle specifically designed to receive letters. Initially, the term was used to describe a box fitted into a door or a wall through which mail could be delivered.
