Numeronym Generator
Make a numeronym: shorten a long word by keeping its first and last letter and replacing the middle with a count of the letters between them. It is the trick behind a11y for accessibility and i18n for internationalization. Type a word or a whole sentence and copy the shortened version.
A numeronym is a word shortened with a number in the middle, so accessibility becomes a11y and internationalization becomes i18n. This generator keeps the first and last letter of each word and counts the letters in between, which is exactly how developers and designers write those well-known abbreviations. Type a single term or a full sentence and the shortened form appears as you go. Short words, numbers and punctuation are left alone, so only the long words get squeezed.

When it comes in handy
Developer shorthand
Write a11y, i18n or l10n consistently instead of typing the long form every time.

Frequently asked questions
- How is a numeronym made?
- You keep the first and last letter of the word and replace everything in between with the number of letters you removed. Accessibility has eleven letters between the a and the y, so it becomes a11y. Internationalization has eighteen letters between the i and the n, giving i18n. The number is a count, not a code.
- Why do short words stay unchanged?
- A numeronym only saves space on long words. Shortening a four or five letter word would barely shrink it and often reads worse, so the standard mode leaves shorter words as they are. If you want every word squeezed regardless, switch to aggressive mode.
- What are common numeronyms?
- The best known come from software: a11y for accessibility, i18n for internationalization, l10n for localization, and k8s for kubernetes. You will also see them used for long product and team names where the full spelling is a mouthful.
