Mac OS X Tiger/Meet the Applications/Dictionary

Possibly the simplest application included with Tiger, Dictionary is the New Oxford American Dictionary’s digital counterpart. Not only can you open it from the Applications folder, but also from inside some other applications, like Safari.

Using it is amazingly easy. Use the search box to find words, or double click a word to look that word up. Use the flippy triangles in the result area to see the Dictionary and Thesaurus entries. Use the back and forward arrows to see words you’ve looked up before. Use the font size buttons (little “A” and big “A”) to adjust the size of the text in the result area.
