It can be really hard to know how to use a word or how they are connected together.  That is why there is a dictionary that can show you how these words are connected just as a native speaker.  If you like colour and a non linear dictionary this is perfect for you.  The name of this dictionary is Visu Words.  As this does not work like a normal dictionary it is important that you look at the legend to understand what these connections are.  It has synonyms as well as other forms of the word and connections.  To experiment with this dictionary visit http://www.visuwords.com/.  The dictionary uses Princeton University’s Word Net as the basis for its dictionary and resources.
