Extraordinarily Useful — But Than a Thesaurus
Nisus Thesaurus relates words by concept more than by equivalence. For example, Looking up "intelligent" provides pathways to words related to "reasoning," "thinking," and "well-informed," plus "healthy," "level-headed," and "sound," the final one being good judgement. The software benefits writers by suggesting alternative ways of viewing and understanding their research and ideas. If you just want different ways of saying things, you might consider the excellent Oxford dictionary and thesaurus built into Mac OS X. Nisus Thesaurus uses the WordNet database from Princeton University. It is an incredible tool for helping you create and refine your writing. Use it alongside a traditional more thesaurus to enrich your communication skills. In defense of Nisus, from a marketing point of view, calling it a thesaurus makes sense, but it is more than a synonym finder.
