Hi, Progress,
I've been looking for that kind of dictionary for years - unsuccessfully. I've also asked in forums - no answer. The only way is to compare the definitions of synonyms, which is not enough to get an ample clear vision of the difference in their usage, with all connotations.
Now that strikes me as very strange - if there's such a huge demand for it, why doesn't anybody take a chance to make a fortune?

It's far from perfect, but worth using: OneLook Reverse Dictionary

Thanks, Tdol,
That's useful, anyway.
