JDictionary is a powerful multi platform dictionary software. It runs on windows, linux, solaris, mac and so on. Note: And naturally on OS/2 with a java runtime 1.3 or higher.

JDictionary is plugin based, and has an easy to use plugin managment system, that is able to download and install the desired plugins automagically from the web. Installing or upgrading one or more plugins (even simultaneously) is just one click!

There are more and more plugins available for jDictionary. It's not necessary for a plugin to be a dictionary related stuff. For example, currently there is a speech synthesizer plugin under development which will be invoked by other plugins to pronounce the desired words.
