There are two built-in spell checker engines available in oXygen (Hunspell and Java spell checker). The two formats of spell dictionaries are different so you need different dictionary files for each spell checker.
This spell checker used in OpenOffice, Mozilla, and Chrome is also available in oXygen and it includes the following built-in dictionaries: English (generic, United States, United Kingdom, Canada), French, German (generic, Germany), Spanish (generic, Spain).
To add a new spelling dictionary to oXygen, or to replace an existing one, follow these steps:
If you cannot find a dictionary for your language, you can build a dictionary that is compatible with Hunspell. Suppose you have a specific list of words that you want to check in your documents when you run the Hunspell checker. You can build a dictionary by following these instructions.
You can download one of the most commonly used dictionaries from the following list. Make sure you read the README file that is included with each dictionary. If you do not accept the license terms for a dictionary, please do not use it.
oXygen provides built-in dictionaries for the following languages: English (United States, Great Britain, Canada), French (France, Belgium, Canada, Switzerland) and German in the form of .dar files located in the following directory: [Oxygen-install-dir]/dicts.
Other dictionaries can be added by copying the corresponding dictionary to the directory [Oxygen-install-dir]/dicts and restarting oXygen. A Java spell checker dictionary is a binary file with the .dar extension and is obtained by compiling a list of the correct words of a language using the Dictionary Builder tool. The user documentation is available with the tool. If you compile a .dar file with this tool and you want to test it in oXygen, just copy the .dar file to the folder [Oxygen-install-dir]/dicts, restart oXygen, and make sure the Java spell checker is selected in Options -> Preferences -> Editor -> Spell Check -- Spell Checking engine.
The following dictionaries are available free of charge and can be installed in oXygen for working with the Java spell checker:
