Functionality

Words can be entered in the search bar by just typing the first few letters. The application will perform an incremental search to show any matching headwords or forms, and will try to bypass spelling errors. Clicking on any word in a definition searches for that word in the dictionary again. Almost any word is clickable, except the pronunciations in phonetic characters and numerals.

The Preferences allow a user to select from three different pronunciation schemes, either US English (Diacritical or IPA), or British English (IPA).

Other languages

As of Mac OS X Leopard, the application includes the Japanese-language dictionary Daijisen

. The Japanese dictionaries do not show up by default, and must be enabled in Preferences.

Software such as DictUnifier can be used to add more dictionaries to the application.

Wikipedia

Leopard also introduced the use of Wikipedia

. However, since the redesign of Wikipedia in the first quarter of 2010, and for participants in the usability study in late 2009, the scrolling functionality of Wikipedia in Dictionary did not work. No scrollbars were present, and users were not able to scroll to parts of the article outside of the constraints of the window size upon loading a Wikipedia article. This error has been fixed since the release of Mac OS X 10.6.5 on November 10, 2010.
