A numeronym replaces the middle of a word with the count of letters it removes, keeping only the first and last letter, the classic examples being i18n for internationalization and l10n for localization.

Why wasn't my short word changed?

Words of three letters or fewer are returned unchanged, since replacing one or two middle letters with a digit wouldn't actually shorten anything meaningful.

Can I convert a whole paragraph at once?

Yes, the tool scans the entire input and replaces every run of four or more letters with its numeronym, so pasting a sentence or paragraph converts every eligible word in one pass.

Does this tool send my text anywhere?

No, the word-shortening logic is a plain string replacement that runs in your browser tab, so the text you type never leaves your device or reaches a server.

Collapse long words into numeronyms

A numeronym keeps a word's first and last letter and replaces everything between them with the number of letters removed, the pattern behind internationalization becoming i18n or accessibility becoming a11y. This tool applies that rule to every word of four or more letters in whatever text you paste, so you can generate a single term or shorten a whole sentence. The conversion runs in your browser as you type; nothing is sent anywhere.

How to use the Numeronym Generator

Type or paste text into the input field.
Every alphabetic word of four letters or longer is converted automatically.
Words of three letters or fewer are left untouched, since there's no middle to count.
Copy the result with the copy button next to the output.

Only ASCII letters A-Z and a-z count as word characters; digits, punctuation and accented letters break a run and are left as-is, so an input like café won't be shortened past its plain-letter portion.
