A numeronym is a number-based word. Most commonly, a numeronym is a word where a number is used to form an abbreviation. Pronouncing the letters and numbers may sound similar to the full word: "K9" for "canine". Alternatively, the letters between the first and last are replaced with a number representing the number of letters omitted, such as "i18n" for "internationalization". Sometimes the last letter is also counted and omitted. These word shortenings are sometimes called alphanumeric acronyms, alphanumeric abbreviations, or numerical contractions. According to Tex Texin, the first numeronym of this kind was "S12n", the electronic mailaccount name given to Digital Equipment Corporation employee Jan Scherpenhuizen by a system administrator because his surname was too long to be an account name. By 1985, colleagues who found Jan's name unpronounceable often referred to him verbally as "S12n". The use of such numeronyms became part of DEC corporate culture. A number may also denote how many times the character before or after it is repeated. This is typically used to represent a name or phrase in which several consecutive words start with the same letter, as in W3 or W3C. Some numeronyms are composed entirely of numbers, such as "212" for "New Yorker", "4-1-1" for "information", "9-1-1" for "help", and "101" for "basic introduction to a subject". Words of this type have existed for decades, including those in 10-code, which has been in use since before World War II. Chapter or title numbers of some jurisdictions' statutes have become numeronyms, for example 5150 and 187 from California's penal code. Largely because the production of many American movies and television programs are based in California, usage of these terms has spread beyond its original location and user population. The concept of incorporating numbers into words can also be found in Leet-speak, where numbers are frequently substituted for orthographically similar letters. Anne H. Soukhanov, editor of the Microsoft Encarta College Dictionary, gives the original meaning of the term as "a telephone number that spells a word or a name" on a telephone dial.
Examples
Where words have multiple meanings, abbreviations such as these are almost always used to refer to their computing sense; for example, G11n for "globalization" refers to software preparedness for global distribution, and not the social trend of globalization. In some cases, the use of appropriate case makes it easier to distinguish between letters such as uppercase I/i and lower case L/l.
