Wikitext is a document written in a wiki markup language, such as the current one explained in Help:Editing (see also Markup spec/DTD). It is a mixture of content, markup, and metadata. The current and old versions of all pages of a wiki are stored in the database in the text table, in the form of wikitext.
- This page could eventually include a complete w:EBNF grammar for the Wikitext language. If you want to work on this, see the two pages mentioned above.
