+**(Web) Accessibility** (often abbreviated to **[A11y](https://www.accessibility.com/glossary/a11y)** — this is a numeronym, where the “11” stands for the 11 letters between the first letter “a” and the last letter “y”) in web development means enabling as many people as possible to use websites, even when those people's abilities are limited in some way.
