Lexipedia is a new online dictionary and thesaurus that visualizes your search. When you type in a word you are presented with related words in a graphical manner with a grid that highlights connections. It includes verbs, adverbs, synonyms and antonyms and “fuzzynyms”...apparently words with a fuzzy semantic relation.
It seems like a useful tool for writing for students, especially those trying to work on college essays.
This site is available in several languages... English, Spanish, French, Italian, German and Dutch.
