Do you use Visualthesaurus.com? (I have no relation to them. Except that I use it! Check it out. when you are looking for that eluding word you have been looking for, its a good choice. The other thing is that it is "visual" in the sense, it's not boring text alone but it shows you words visually. If you are a visual person (just like I am), it could be the tool you are looking for. Have a good time.
