WordNet 3.0 Vocabulary Helper

This seems like an interesting tool, WordNet 3.0 Vocabulary Helper. Wikipedia defines WordNet as something which “groups English words into sets of synonyms called synsets, provides short, general definitions, and records the various semantic relations between these synonym sets.”

Created at Princeton University for research in Machine Translation. An offline version can be downloaded from the official Princeton University website.
