Your next dictionary of choice? VisuWords – Visualizing words in a visual online graphical dictionary. Linking words together finding similar meaning, or suitable verbs or nouns that are connected to the word you chose to lookup.
VisuWords uses an open source database called WordNet. I previously was a fan of dict.org, however I do like visualization ref.: Bubbl.us Online Mapping, and I think that this graphical dictionary will prosper.
(Found VisuWords via. Del.icio.us.)
Thanks for the great tool! I’ll try to use it. By the way, as for languages, I also use other online tools, such as thesaurus dictionary.
