The word "tommygun" is a colloquial term for a submachine gun. It is spelled with two m's, as indicated by the International Phonetic Alphabet (IPA) phonetic transcription /ˌtɒmiˈɡʌn/. The double m represents the nasal sound made by the pronunciation of the letter "m" in the word, which sounds like "mmm". The spelling of "tommygun" is a result of colloquial pronunciation and spelling conventions rather than formal English rules. The term has its origins in the weapon's use by gangsters in the 1920s and 1930s.
Tommygun, also known as a Tommy gun or a Thompson submachine gun, is a type of portable automatic firearm that was developed in the early 20th century. It was named after its primary inventor, John T. Thompson, who designed and patented the weapon in 1919.
The Tommygun is characterized by its compact size, relatively high rate of fire, and use of pistol ammunition. It typically has a vertical foregrip and a drum or box magazine that can hold a large number of rounds, usually .45 ACP cartridges. This design feature allows for sustained fire without frequent reloading.
Originally intended for military use, the Tommygun gained notoriety during the prohibition era in the United States (1920s-1930s) when it became a favored weapon among both law enforcement and organized crime groups. Its rapid-fire capability made it highly effective in close-quarter combat and its distinctive appearance helped solidify its presence in popular culture.
In modern times, the Tommygun has largely been replaced by more advanced firearms, but it remains an iconic symbol of the Roaring Twenties and the era of gangsters and prohibition. It is often seen in movies, video games, and other forms of media that depict the era. Despite its historical significance, the Tommygun is now primarily known as a collector's item or a cultural reference, rather than a commonly used firearm.
