A numeronym is a number-based word. Most commonly, a numeronym is a word where a number is used to form an abbreviation (albeit not an acronym or an initialism). Pronouncing the letters and numbers may sound similar to the full word: "K9" for "canine" (phonetically: "kay" + "nine"). A similar example in French is "K7" for "cassette" (phonetically: "ka" + "sept"). Alternatively, the letters between the first and last are replaced by a number representing the number of letters omitted, such as "i18n" for "internationalization". Sometimes the last letter will also be counted and omitted. According to Tex Texin, the first numeronym of this kind was "S12n", the electronic mail account name given to DEC employee Jan Scherpenhuizen by a system administrator because his surname was too long to be an account name. 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.
