Terminology for OS X Dictionary

Terminology for OS X Dictionary

Terminology for iOS is based on WordNet, a great semantic lexical reference. We do not offer a full Mac app for Terminology, but have prepared a dictionary using this same great data for use in the built-in OS X Dictionary app.

Terminology for OS X is not an app, and does not have some of the features of the iOS version. It is, however, a great resource and the integration with the OS X Dictionary makes it work great with contextual "Look up..." commands and other integrations provided by the Dictionary app.

Installation and Activation

To install Terminology for OS X Dictionary (instructions also in README in download):

  • Download the Terminology for OS X zip file and uncompress it.
  • Double-click the "Install.command" script to copy the "Terminology.dictionary" file to the hidden ~/Library/Dictionaries folder. This will install the dictionary for use by the current user. Alternately you may copy this file to ~/Library/Dictionaries manually – or to /Library/Dictionaries to install for all users. (These folders are hidden by default on OS X.)
  • Open the Dictionary app (in "Applications" folder).
  • Open Dictionary app preferences and check the "Terminology" dictionary to activate it.
  • Optionally, drag to arrange the priority of your installed dictionaries in this preferences list.
  • "Terminology" will now appear as one of your dictionary search options in the dictionary app.

Known Issues

There are not any "known issues", per se, but I also did not spend a lot of time testing. Please feel free to offer feedback. The OS X Dictionary formats are not super-well documented, but I tried to make it fit into the look and feel of the existing dictionaries.
