Thinkmap Visual Thesaurus
The Visual Thesaurus is an interactive dictionary and thesaurus which creates word maps that blossom with meanings and branch to related words.
Its innovative display encourages exploration and learning. You'll understand language in a powerful new way. Say you have a meaning in mind, like "happy." The VT helps you find related words, from "cheerful" to "euphoric." The best part is the VT works like your brain, not a paper-bound book. You'll want to explore just to see what might happen. You'll discover -- and learn -- naturally and intuitively. You'll find the right word, write more descriptively, free associate -- and gain a more precise understanding of the English language. The Visual Thesaurus is also available in the Desktop Edition
