The OpenThesaurus German Dictionary Plugin (formerly Thesaurus Deutsch) extends Apple’s Dictionary application (Dictionary.app) with a German thesaurus.

• You can search for every synonym not just the primary word.
• You can search for parts of a hyphen delimited term or a word which is not located at the beginning of a term (as Dictionary normally does).
• This is a offline dictionary, so you don’t need an internet connection.

The dictionary content is based on the online dictionary www.openthesaurus.de by Daniel Naber.
