This plugin will display a small ??? icon that links to either the definition or the translation of the word. The plugin is a no-brainer to use: [define:dog] will define the word ?dog? and [en2fr:dog] will translate the word ?dog? from english to french. [wikies:dog] will show the Wikipedia article for the given word in spanish (es). Dictionary.com is used to define words, as it has definitions for technical terms too. Translation works with Google’s translation engine.
