The dictionary that the spelling checker uses is used based on the currently chosen content culture. If no dictionary is available for the current content culture, the default dictionary is used. You can specify the default spelling checker dictionary in the **CMSDefaultSpellCheckerCulture** configuration key in the **appSettings** section of the **web.config** file. ## Adding additional dictionaries The dictionaries are stored in folder **\App\_Data\Dictionaries**. If you need additional dictionaries, you can download them from the following URLs: - CS-cz: - DE-de: - EL-gr: - EN-au: - EN-ca: - EN-gb: - EN-us: - ES-es: - ES-mx: - FR-fr: - IT-it: - NB-no: - NL-nl: - NN-no: - PL-pl: - PT-pt: - RO-ro: - RU-ru: - TH-th: Once downloaded, unpack them to the dictionary folder -  **\App\_Data\Dictionaries**. The file name of the dictionary must match the culture code of the currently edited content - e.g. fr-fr. Then, restart the website using the System application.
