I am looking at the [url=http://en.wikipedia.org/wiki/DICT_clientlist of available free DICT dictionaries[/url] to be run by gnome-dictionary, and the selection doesn't seem to be all that great. The 1913 dictionary has too many flaws in it from what I can tell...flaws are exactly what I am trying to prevent when I seek out an entry in a dictionary.

Does anyone know where to obtain a quality, English dictionary that I can somehow run on Linux, without relying on WINE? I am willing to even pay money for a commercial dictionary software if it will run with Linux and if it has professional entries.

Most people install gdict. It's the 1913 dictionary supplemented by much updating from more modern sources. There are many others available as well. I assume that you know that a local dictionary, such as gdict is not very useful unless you have also installed the server, dictd. If I knew what distro you intended to run it on, that would be helpful for more specific suggestions.

In Debian ... "aptitude search dict" will offer a multitude of options.
