This page is protected against creation This page has been deleted and cannot be created without administrator help; by far the most common reason for this to happen is that it has been repeatedly created by spambots and has been protected to prevent those spambots attacking it in the future. If you do need to create a page at this title, place a request for the page to be unprotected (for instance at the Talk page of the administrator who protected it; check this page's history to find out who that was).

This page is a WIP, but the language is not. Please consult the talk page before making any major changes.

The title of this article is not correct because of technical limitations. The correct title is actually {{{title}}}.

This page does not exist yet. You can create it via typing in the box below (see the help page for more information). (If you don't want to create the page, just navigate away, e.g. with your browser's back button.) Note: if this is your first contribution to the wiki, you will have to introduce yourself first, due to problems we're having with spambots.

When creating a new page, it is recommended that you:

• Make sure it's linked to from the rest of the wiki. If you're creating a language, you'll typically link to it from the language list or joke language list. (If you got here by following a link from another page, or via a tab at the top of the page, you probably don't need to do anything here.)
• Place the page in appropriate categories (to place a page in a category, add [[Category:name of category]] at the bottom of the page). See Esolang:Categorization for a list of the categories you can use. (This does not apply to things like talk pages.)

This will make it easier for people who are interested in your page to find it.

Thanks for contributing to Esolang! A programming language is an artificial language for expressing computer programs. This is a list of esoteric languages that are completely unusable for programming even in theory, trivial and less interesting variations on existing esoteric languages, or too underspecified to determine any potential usability. Generally speaking, they are not of any interest except for potential humor value.

For esoteric languages that are potentially interesting in some way, or that are actually capable of running programs and producing a useful output, see the normal list of esoteric languages.

Like for that other list, items here will eventually be removed if they don't link to a page on this wiki.
