On Wikipedia, an essay is a page written in Wikipedia project namespace describing the processes on Wikipedia at the point-of-view of one or more users. Essays can be written by anyone and can give instructions or advice, can be long or short, serious or funny.
There are currently thousands of essays, and this number is expected to grow. Essays vary in popularity and how much they are followed and referred to. As with WikiProject pages, information pages and template documentation pages, essays have not been formally approved by the community, thus generally have limited status during deliberations (see WP:Local consensus for details).
