OpenThesaurus German


This plugin extends Apple‘s Dictionary application ( with a German thesaurus.

  1. You can search for every synonym not just the primary word.

  2. 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).

  3. You don‘t need an internet connection, because the dictionary is included in the plugin.

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


The installation is very easy. Just download the disk image and follow the included instructions.


You can uninstall the plugin by deleting OpenThesaurus Deutsch.dictionary from
/Library/Dictionaries or ~/Library/Dictionaries.
