Manual:Glossary

 ''Note: While the definitions below may be useful for understanding and communicating on project namespace and discussion pages. Remember to explain jargon in manuals and MediaWiki software documentation, and write them in language which is readily understandable without specific knowledge of the MediaWiki software.''

Do not overdo the use of MediaWiki or Wikipedia jargon, at least not without providing explanatory links to the appropriate pages.

This is a glossary of terms commonly used in MediaWiki and on the MediaWiki wiki. For most recent glossary efforts, see also Terminology. For more help, see Project:Help, developer hub, sysadmin hub, or user hub.

A

 * Academic wikis
 * Third-party wikis meant to be used in an academic context with a greater emphasis on features like access control, content approval, and research analysis.   See also: Academic hub


 * Admin
 * Short for Administrator. A user with extra technical privileges for "custodial" work on MediaWiki wikis – specifically, deleting and protecting pages, and blocking abusive users.


 * Anon
 * Abbreviation for "anonymous user". As a user does not necessarily lose his or her anonymity by registering or logging in, this term should be avoided. See IP user.


 * Archive
 * A subpage of a Talk page to which some parts of the discussion are transferred, to reduce the size of the Talk page. Rarely, the term may refer to the an historical archive page, for outdated historical material related to MediaWiki.

B

 * Ban
 * Banning is the extreme, last resort action by which someone is prevented from editing a wiki for a certain length of time, limited or unlimited. Banned users are not necessarily blocked, however, it is one mechanism to enforce a ban. See also: Block.


 * Block
 * Action by an administrator, removing from a certain IP address or username the ability to edit a wiki. Usually done against addresses that have engaged in vandalism or against users who have been banned. See also: Ban.


 * Blue link, bluelink
 * A wikilink to an article that already exists shows up blue (or purple if it has been recently visited by that reader/editor). See also Sea of blue, and red link.


 * Blurb
 * A short (one sentence) summary of a recent news item for ITN.


 * Boilerplate text
 * A standard message which can be added to an article using a template.


 * Bot
 * A program that automatically or semi-automatically adds or edits Wikipedia-pages.


 * Broken link
 * A link to a nonexistent page, usually colored, depending on your settings. May also refer to dead links. See also: edit link, and red link.''


 * Broken redirect
 * Redirect to a non-existing page. Common opinion is that these should be removed.


 * Bureaucrat
 * A MediaWiki administrator who has been entrusted with promoting users to Administrator status. See also Crat, and Project:Bureaucrats.

C

 * Cabal
 * Sometimes assumed to be a secretive organization responsible for the development of Wikipedia, the word is usually used as a sarcastic hint to lighten up when discussions seem to become a little too paranoid. Discussions involving the term may have links to admin problems or pretty much anything to do with the foundation of Wikipedia. The term TINC ("There Is No Cabal") is occasionally encountered, used humorously in such a way as to suggest that maybe there is a cabal after all. The term is comparable to the use of the term SMOF in science fiction fandom. Compare Troll. See also Cabal, There Is No Cabal.


 * CamelCase
 * CamelCase (camel case or camel-case)—originally known as medial capitals—is the practice of writing compound words or phrases in which the elements are joined without spaces, with each element's initial letter capitalized within the compound and the first letter is either upper or lower case—as in "LaBelle", BackColor, "McDonald's" or "iPod".


 * Canvassing
 * Canvassing is sending messages to multiple Wikimedians with the intent to inform them about a community discussion. Under certain conditions, canvassing is acceptable to notify other editors of ongoing discussions (see Friendly messages), but inappropriate messages, written to influence the outcome rather than to improve the quality of a discussion, are considered disruptive since they compromise the consensus building process.


 * Cat, cat.
 * "Category" or "categorize". Often pluralized as "cats" or "cats."


 * Category
 * A category is a collection of pages automatically formed by MediaWiki by analyzing category tags in articles. Category tags are in the form Category:Extensions. The part after the ":" is the name of the Category. Adding a category tag causes a link to the category and any super-categories to go to the bottom of the page. As stated, it also results in the page being added to the category listing.


 * Category declaration
 * A category name placed at the bottom of any page. Pages are made members of categories by the use of the category declarations. Some people refer to category declarations as category tags. A category declaration looks like where foo bar is the title of the category page.

 * A humorous way of indicating that someone has over-reacted during an argument such as an edit-war in order to gain some advantage.


 * cmt
 * Comment.


 * Comment out
 * To hide from normal display whilst retaining the material for editors to see. This is done by inserting the characters at the end. These character strings are used to delimit comments in HTML code.


 * Commons
 * Wikimedia Commons is an online repository of free-use images, sound and other media files. It is integrated into MediaWiki wikis through the use of InstantCommons.


 * Consensus
 * The mechanism by which many (but not all) decisions within Wikimedia Foundation projects are nominally made. Not the same as a "majority vote".

 * Cut-and-paste move, cut and paste move, cut 'n' paste move, cut-n-paste move, etc.
 * Moving a page by taking the text of the page, and putting it into the edit window for the second page. Generally considered worse than the 'move page' option, because it splits the page and its edit history. Cut and paste moves can be fixed by administrators.

 * Diff
 * The difference between two versions of page, as displayed using the Page history feature, or from Recent Changes. The versions to compare are encoded in the URL, so you can make a link by copying and pasting it – for instance when discussing a change on an article's talk page.


 * Double redirect
 * A redirect which leads to another redirect. Counterintuitively, this will not bring one to the final destination, so it needs to be eliminated by linking directly to the target redirect. Double redirects are generated when moving a page that has redirects leading to it. See also Repoint.


 * Dupe
 * Short for a duplicate article. Often used when identifying a duplicate page that needs to be merged with another.

E

 * EC, ec, e.c., Ec, (e/c), etc.
 * Same as Edit conflict.


 * Edit conflict
 * Also, rarely "edconf". Appears if an edit is made to the page between when one opens it for editing and completes the edit.

 * Foo
 * A placeholder name, used to provide a generic example. Thus, "an article on the culture of Foo", means "an article on the culture of any of the places under discussion, or any that it may also apply to". When two placeholders are required, Bar is usually used as the second (e.g., "an article on the Foo of Bar").


 * fmt
 * Format. Abbreviation commonly used in edit summaries to signify formatting of the page, or wikification.


 * Free link

Unless otherwise specified in a user's monobook.css, these links usually show up as blue if they are working and you haven't visited them before, red if they are broken, and purple if they are working and you have visited them before; note that they do not have the arrow symbol characteristic of an external link.


 * Friendly notices

Godwin's Law is: "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1." It is often cited as soon as it occurs as a flag that discussions have gone on too long or gotten out of hand on a particular topic.


 * Google test
 * Running sections or titles of articles through the Google search engine for various purposes. The four most common are to check for copyright violations, to determine which term among several is the most widely used, to decide whether a person is sufficiently notable to warrant an article and to check whether a questionable and obscure topic is real (as opposed to the idiosyncratic invention of a particular individual).
