how to get an actual dictionary in libre office?
 

Not a dictionary just for spell checking or a thesaurus, but an actual dictionary that I can click on the word and it will give me the definition. Does LibreOffice have any way of doing that? Or is there some other way of checking a definition quickly and easily (not googing or leaving the page) while I'm working in libreoffice? Thanks.

I'm not aware of anything in Libre Office, but Xfce has a dictionary, available in xfce-goodies, that does what you want. If you run Xfce, you could open the dictionary, which is a small resizable window, and use it for definitions. You can type or paste in a word and get the standard definitions, either online or offline. It's fairly configurable, and should do what you want. If you're running Gnome, I don't know, there might be something available. For other desktop environments, I have no clue.

I do not know of a Libre Office plugin that provides a literal dictionary aside from spell checking, however the XFCE Dictionary is quite good and you could leave that running in the background and switch over to it when needed. That's pretty much what I do.

There's also a KDE Plasmoid dictionary, if you're running KDE, that would provide the same thing.

Edit: seeing that sgosnell just recommended the same thing, I should not that you do not have to be running XFCE to use its dictionary app. I use it independent of XFCE regularly.

Thanks. I do have Xfce and the dictionary that was preinstalled is great. Excellent suggestion. That's just what I'll do.

Thanks notKlaatu. I have checked the dictionary out in XFCE and I think it's the best online dictionary I've ever come across. Really appreciate the help. Thanks a lot.

Glad you like it! I felt the same about it, and I love dictionaries so my standards are high :-)
