The term "letter bomb" refers to an explosive device concealed inside a package or envelope that is sent through the mail. The word "letter" is spelled with two syllables: /ˈlɛtər/. The first syllable, "let," is pronounced with an open E as in "red," while the second syllable, "ter," is pronounced with a schwa sound, like the "er" in "butter." The word "bomb" is spelled with one syllable: /bɑm/. This is pronounced with a short A sound as in "palm." Together, the two words create a compound noun that describes a dangerous weapon.
A letter bomb refers to an improvised explosive device (IED) that is designed to be sent via mail or courier services with the intention of causing harm or destruction upon its opening. It is a deadly and clandestine weapon that typically comprises explosive materials, such as gunpowder or other volatile substances, enclosed within a package or envelope disguised as a conventional letter or parcel.
The term "letter bomb" is derived from the fact that it primarily targets individuals by sending them explosive devices concealed within a seemingly innocent letter, thereby posing a significant threat to the personal safety of the intended recipient. The motivation behind such attacks can vary, ranging from acts of terrorism, targeted violence, blackmail, or revenge.
Letter bombs often exhibit various characteristics, such as excessive weight, strange odors, unusual markings, or protruding wires, which may arouse suspicion upon close inspection. These devices, once triggered, usually employ mechanisms like pressure switches, timers, or impact sensors to initiate the explosion upon opening the package.
Due to their inherent risks and potential to cause severe injury or death, letter bombs constitute a serious threat to public safety and security. Countermeasures and safety protocols have been developed to detect and prevent their circulation, including the use of X-ray scanners, trained dogs trained to detect explosives, and stringent mail screening procedures.
The term "letter bomb" is derived from the combination of the words "letter" and "bomb".
The word "letter" originated from the Old French term "lettre" and the Latin word "littera". It originally referred to a written message or a written or printed communication sent from one person to another. Over time, it extended to encompass various types of written documents, including personal letters, business correspondence, and official communications.
The word "bomb" has its roots in the Latin word "bombus", which referred to a booming sound. It evolved to denote an explosive device designed to cause destruction and harm when detonated. The term "bomb" made its way into English in the 17th century, borrowed from the French word "bombe".
