LanguageTool: An Open Source style and grammar checker for English, French, German, Polish, Dutch, Romanian, and other languages. You can think of LanguageTool as a software to detect errors that a simple spell checker cannot detect, e.g. mixing up there/their, no/now etc. It can also detect some grammar mistakes. It does not include spell checking.

LanguageTool will only find errors for which a rule is defined in its XML configuration files. Rules for more complicated errors can be written in Java.

LanguageTool requires an external link to Java 5.0 or later. The current version only works with 3.0.1 or later and LibreOffice and you need to restart after installation of this extension.

Installation and Usage

In Double click LanguageTool-1.3.1.oxt to install it. If that doesn't work, call Tools -> Extension Manager -> Add... to install it. Close and re-start it. Type some text with an error (e.g. "This is an test." – make sure the text language is set to English) and you should see a blue underline.

Also see Usage for using LanguageTool outside of

Thought it might be nice to have instructions on how to install Sun Java 6, as located here...… – Alex Stevens Jun 6 '11 at 23:49

The LibreOffice grammar checker Lightproof is already packaged in the repositories, and is easy to install. Install the package libreoffice-lightproof-en (or -hu for Hungarian or -ru-ru for Russian), and restart Libreoffice if it’s running.

Note that the available grammar checks are more limited than in MS Office, so if it seems to not be working, that might be the reason. Try “and and”, which should get a wavy blue underline if it’s working.
