Install Dictionary

The Hunspell plugin does not include any bundled dictionaries. You need to install dictionaries separately.

You can download good dictionaries from the project, which also uses the Hunspell engine. There is a list of available dictionaries at

The file you downloaded will have an .oxt extension. If you rename this extension to .zip, you can unzip it. You need the .dic and .aff files for your language (e.g. en_US.aff and en_US.dic for American English). Copy these files to a safe location (the dictionary file path).

Configure the Dictionary

Open the Spelling preference page: Window > Preferences > General > Editors > Text Editors > Spelling Next, enter the dictionary file path.
