Lingo is a glossary extension. It lets you define a list of abbreviations and their definitions on a page and then displays these definitions whenever an abbreviation is hovered over in an article.


The Terminology page[edit]

By default Lingo will mark up any page with the terms and definitions defined on the Terminology page of your wiki (or the respective page in the language of your wiki; see the Special:Version page of your wiki for the actual Terminology page name). Just create that page and insert some entries using the following syntax:

;FTP:File Transfer Protocol
;AAAAA:American Association Against Acronym Abuse
;AFAIK:As Far As I Know
;AWGTHTGTATA:Are We Going To Have To Go Through All This Again
;HTTP:HyperText Transfer Protocol

You can use any characters in a term (including punctuation, spaces, all UTF-8 characters, but excluding the colon (:) of course), you are not limited to only letters.

To give some structure to the Terminology page you are also allowed to have Terms and Definitions on separate lines. Any lines not starting with a ; or a : are ignored, so go ahead and insert empty lines, headlines, explanatory text.

Using this format you may assign one definition to multiple terms, e.g. to cover grammatical variants (see the U.S.A. example below) and multiple definitions to one term, e.g. to cover different meanings (see the ACK example). You may even combine this, i.e. have multiple definitions for a set of multiple terms. Finally you may also use transclusion, e.g. to have different glossaries for different topics and pull them all together on the Terminology page.

:File Transfer Protocol

:American Association Against Acronym Abuse

:Acklington railway station

:United States of America

Pull in more terminology from elsewhere:

Excluding text from markup[edit]

You can exclude an article from markup by including the magic word __NOGLOSSARY__ anywhere in that article's text.

In some cases it may be necessary to exclude only portions of a page, e.g. because Lingo interferes with some JavaScript. This can be achieved by wrapping that part in an HTML element (e.g. a span or a div) and specifying class="noglossary". As a shorthand for <span class="noglossary"> you can just use the <noglossary> tag.


Lingo supports the ApprovedRevs extension for the Terminology page. See Customization below.


The extension is pretty well internationalized by now, thanks to the efforts of the volunteers on https://translatewiki.net. (If your language is not supported yet, get an account there and help yourself. It's easy!) To find out the name of the Terminology page and of the __NOGLOSSARY__ magic word in your wiki's language, have a look at the files in the i18n folder and the Lingo.i18n.magic.php file.


Lingo 3.0 requires MediaWiki 1.27 or above.


Lingo should be installed using Composer. The package name is mediawiki/lingo. For instructions on how to install Composer see MediaWiki's Composer User manual .

  1. Add the following to the MediaWiki composer.local.json file
    	"require": {
    		"mediawiki/lingo": "~3.0"
  2. Run php composer.phar update mediawiki/lingo from the MediaWiki installation directory.
    Any future update is then just a call to php composer.phar update mediawiki/lingo.
  3. Add to the end of LocalSettings.php:
  4. Do some customization if necessary (see below)
  5. Go to the Special:Version page of your wiki and verify that an entry for Lingo exists
  6. From Lingo's entry on the Special:Version page follow the link to the Terminology page of your wiki and insert some entries OR (if this page exists already) edit and re-save it to trigger the recreation of the glossary

Using packaged downloads[edit]

If Composer is not an option, you may also install it like this:

  1. Download Lingo 3.0.0 or the current development version (Alternatively you can clone Lingo using git.)
  2. Extract the files to the $IP/extensions directory
  3. If necessary rename the newly created directory to Lingo
  4. Add to the end of LocalSettings.php:
  5. Do some customization if necessary (see below)
  6. Go to the Special:Version page of your wiki and verify that an entry for Lingo exists
  7. From Lingo's entry on the Special:Version page follow the link to the Terminology page of your wiki and insert some entries OR (if this page exists already) edit and re-save it to trigger the recreation of the glossary


Add the following to LocalSettings.php and uncomment/modify as needed:

$wgHooks['SetupAfterCache'][] = function() {

    // specify a different name for the terminology page (Default: 'Terminology' (or localised version). See MediaWiki:Lingo-terminologypagename.)
    //$GLOBALS['wgexLingoPage'] = 'Terminology';

    // specify that each term should be annotated only once per page (Default: false)
    //$GLOBALS['wgexLingoDisplayOnce'] = false;

    // specify what namespaces should or should not be used (Default: Empty, i.e. use all namespaces)
    //$GLOBALS['wgexLingoUseNamespaces'][NS_SPECIAL] = false;

    // set default cache type (Default: null, i.e. use main cache)
    //$GLOBALS['wgexLingoCacheType'] = CACHE_NONE;

    // use ApprovedRevs extension on the Terminology page (Default: false)
    //$GLOBALS['wgexLingoEnableApprovedRevs'] = true;


MobileFrontend suppresses Lingo's styling, which makes all Definitions used on the article appear at the end of the page. To avoid this add the following to your LocalSettings.php when using MobileFrontend:

$wgMFRemovableClasses = [ 'base' => [ '.mw-lingo-tooltip' ] ];

Lingo also provides an interface to plug in alternative dictionaries (backends). If you are interested in that, see Semantic Glossary for an example. You can also drop me a mail.

Finally you can provide your own styling. For the classes used by Lingo for the various HTML elements, please have a look at the style file.
