FAQ
What is a numeronym?
A numeronym is an abbreviation that keeps the first and last letters of a word and replaces the characters in between with their count. For example, internationalization becomes i18n: an i, 18 letters, then an n.
What do i18n and l10n stand for?
i18n is short for internationalization and l10n is short for localization. Both are common in software development.
Is there an official standard for numeronyms?
There is no unified standard, but forms such as i18n, a11y, and k8s are established industry conventions. This tool follows the common rule of keeping the outer letters and counting the middle ones.
What happens with short words of fewer than four letters?
Words shorter than four letters are usually left alone, because the numeronym would be no shorter or would lose all meaning, so the tool returns them unchanged or flags them.
