Web of Words

WordNet® is “an online lexical reference system whose design is inspired by current psycholinguistic theories of human lexical memory. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one underlying lexical concept. Different relations link the synonym sets.”

With a suitable interface, this synonym web makes a handy thesaurus/dictionary. WordWeb is a nice thesaurus/dictionary program for Windows that uses the WordNet database — and as the lite version of WordWeb Pro, it’s freeware.

For portability, there’s Noah Lite for PalmOS. I’ve tried it and liked it, but haven’t used it as much as WordWeb. There’s also RoadLingua for PalmOS and PocketPC, which I haven’t tried yet.

For Mac OS X, try WordNet.app.
