I have been searching for a free and good English to English Dictionary for linux that can be used locally...
But Alas after searching out loud ... I found only one dictionary called QEverest which was not satisfactory at all..

So I installed a free windows dictionary using Wine it is called WordWeb 3.02..
It is very good. It has illustrations too.

So here how I have installed It:
*********************************

First I have Downloaded Wordweb setup file from wordweb.info
Then have installed it in my Windows box.

I install it with the default condition so it was in
C:\Program Files\WordWeb
and there it spitted a few files
and it also throws a .dll file in the C:\Windows\
it is wweb32.dll
********************************
Then I came back to my Linux box I use SUSE Pro 9.3
opened up a terminal and run wine for the fist time..
It created a folder
~/.wine/
then again ran wine at the terminal but this time I passed the setupfile of wordweb as an argument

e.g. >wine wweb301.exe
installation wizard came up same as I have seen at the windows box..
I follwed the wizard..
I chose the notray option
I created the following folder
~/.wine/drive_c/Program\ Files/WordWeb/
and it would throw wwnotray.exe and uninst.exe
again back to the windows box and copied all the extra files I saw in the Wordweb folder and paste it into my linux box 'WordWeb' folder
here actully I had to copy only the wweb.ww3 file for the dictionary but I also copied all the help files so that the program gives me all the help topics too
***********
then I copied wweb32.dll file from C:/windows/ to my
~/.wine/windows/

now I went to the wine folder using the terminal and typed
>wine wwnotray.exe ................ That's it.

you can creat a shell script for that and put it in you path so that next time you don't have to go to the .wine folder again..
heres the script:
####################################
#!/bin/bash
#It runs the WordWeb
wine ~/.wine/drive_c/Program\ Files/WordWeb/wwnotray.exe
##############################################

you might have to download or get the windows fonts too.. otherwise fonts may be too small for you but I don't mind

Hopefully this might help someone... I am a newbie...I have gotten a lots of support from the Linux Community... So I wanted to return a little...
Thank you.

Oh wow!.....that's really a nice post!

Since I have an internet connection, and Use KDE in RH9, I use Kdict, the online dictionary. However, I was using Word Web in RH9, when I did not have an internet connection.

Good....!!!

Try Wordnet english dictionary.

Thanks, I am not allowed to post any URLs right now...

I'm using StarDict on openSUSE 10.2 - http://stardict.sourceforge.net/

Most people would probably just install dictd, and whatever dict-compatible dictionaries they wanted.

Instead of running WordWeb on Wine, one may use Artha -> http://artha.sourceforge.net/ which is written especially for Linux (open-cource) and is equivalent to WordWeb PRO in Windows I.e. it has the regex based search feature which only available in the pro version of WordWeb.
