it is a great name, maybe dictionary.com might even buy it from you , who knows lol,
i think one interesting way to develop this could be to have all kinds of adjectives.. prob the most commonly used ones, but thats still in the thousands... and put a picture with the definition that would perhaps illustrate best what the definition is implying, for example , happy - would have a happy person pic next to it, confused... would have a face of someone who's confused lol, basic idea, to make something that's actually interesting to see as opposed to the dictionary's monotone definitions...
good luck, if something like fashionfind.com can go for thousands on sedo... this could definately go for 25 000- 30 000$
