Terms and Definitions Dictionary free WordPress plugin

This plugin creates a complete Dictionary on your site. It defines a new post type, Definitions, and its own taxonomy, Families (of Terms and Definitions). This plugin is very useful if you need to explain to your visitors technical words or something else, just moving their mouse over the word. It is fully configurable along its options page: color, size, movement, effects, autodetection… For adding a definition to your post, first, you must create the definition in the Definitions section. After that, go to your post, and write “[def]Term[/def]”, where Term is the title of your definition (or the slug, or the ID, if you have configured the plugin that way). It allows .mo and .po translation files. The plugin supports: English, Spanish. Italian, Brazilian Portuguese and Portuguese (Thanks to Javier Valenzuela!).
