where you can type a basic meaning and it will suggest a possible list of words that match? many times i know what i'm trying to say but lack the particular word to describe my thought. i thought with the sophistication of search engines nowadays it might exist online somewhere? sometimes i can stumble/bumble my way to a word through a thesaurus but it would be so much easier if there was something similar to Ask.com where instead of a question you type as much of a meaning/definition as you can describe.
