Just in case anyone has to deal with web developers or agencies or geeks you may find this useful.
Numeronyms are words with all the letters in the middle replaced with a number. This number is the amount of letters that have been removed. Here's an example:
- Usability becomes u7y
- Accessibility becomes a11y
If you are talking about implementing a content management system you may find references to i18n or L10n (Internationalisation or Localisation).
I hope this helps.
