Anumeronym is a word, usually an abbreviation, composed partially or wholly of numerals. The term can be used to describe several different number-based constructs, but it most commonly refers to a contraction in which all letters between the first and last of a word are replaced with the number of omitted letters (for example, "i18n" for "internationalization").[1] According to Anne H. Soukhanov, editor of the Microsoft Encarta College Dictionary, it originally referred to phonewords – words spelled by the letters of keys of a telephone pad.[2]
A numeronym can also be called an alphanumeric acronymoralphanumeric abbreviation.
A number may be substituted into a word where its pronunciation matches that of the omitted letters. For example, "K9" is produced "kay-nine", which sounds like "canine" (relating to dogs).
Examples of numeronyms based on homophones include:
Alternatively, letters between the first and last letters of a word may be replaced by the number of letters omitted. For example, the word "internationalization" can be abbreviated by replacing the eighteen middle letters ("nternationalizatio") with "18", leaving "i18n". Sometimes the last letter is also counted and omitted. These word shortenings are sometimes called numerical contractions.
According to Tex Texin, the first numeronym of this kind was "S12n", the electronic mail account name given to Digital Equipment Corporation (DEC) 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" (ess-twelve-en). The use of such numeronyms became part of DEC corporate culture.[3]
Examples of numerical contractions include:
Some numeronyms are composed entirely of numbers, such as "212" for "New Yorker", "4-1-1" for "information", "9-1-1" for "help", "101" for "basic introduction to a subject", and "420" for "Cannabis". 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.

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 (World Wide Web) or W3C (World Wide Web Consortium).
Numeronyms can also make use of SI prefixes, as are commonly used to abbreviate long numbers (e.g. "1k" for 1000 or "1M" for 1000000).
Examples of numeronyms using SI prefixes include
K8s is just an abbreviation of Kubernetes ("K" followed by 8 letters "ubernete" followed by "s").
Some scientists have come to abbreviate the volcano as E15, for the 15 letters that follow the E
