Numeronym Generator
TextConvert words to numeronyms like i18n, k8s, a11y and l10n for compact abbreviations, and batch convert a list while keeping the original casing and separators.

About Numeronym Generator
You have surely seen forms like i18n, a11y, and k8s - these are numeronyms, where the middle letters of a word are replaced by their count while the first and last letters stay. This tool batch-generates them locally in your browser: enter one word per line and it outputs "first letter + middle letter count + last letter", along with how many characters you saved. It is perfect for giving long technical terms a short, memorable alias. Because the middle letters are discarded in favor of a count, a numeronym is deliberately lossy and therefore one-way: it is a mnemonic alias, not an encoding, so reverse lookup only works against a common-words table, and collisions (different words sharing the same first, last, and length) are inevitable - disambiguate using context. Many words already have accepted conventions (i18n, l10n, a11y, k8s, o11y), and following those instead of inventing fresh forms makes your output easier for everyone to read and search. Handy whenever you want to check a spelling before putting a long word into a slide or project codename, with no data leaving your device.

Use Cases
- Tech aliases — Shorten internationalization to i18n for consistent use across code and docs.
- Variable names — Create compact identifiers for long concepts as namespace or config-key aliases.
- Team glossary — Batch-build abbreviations for accessibility, localization, and more to align team wording.
- Chat shorthand — Use k8s, o11y, and similar in messaging to type less and communicate faster.
- Compact labels — Give long words short tags in boards or filenames to save display space.
- Project codenames — Turn long project names into short numeronyms for internal board labels and sprint identifiers.
- Log tag compaction — Shorten verbose component names in log output to make log lines more readable at a glance.
FAQ
Are words shorter than four letters abbreviated?
No. Very short words save nothing and only get harder to read, so the tool keeps them unchanged.
Why is the middle of i18n 18?
internationalization has exactly 18 letters between the first i and last n; the rule is "first letter + middle count + last letter."
Can two words collide?
Yes. Different words with the same first and last letters and length produce the same numeronym, so rely on context to disambiguate.
Can it process many words at once?
Yes. Enter one word per line for batch output and copy all results with one click.
Are there common conventions I should follow?
Yes. Conventions such as i18n, l10n, a11y, k8s, and o11y are widely accepted; following them beats inventing new forms for readability and search.
Can it be reversed?
No. A numeronym drops the actual middle letters and cannot uniquely restore the original - it is a mnemonic alias, not an encoding.
