Note: Not all applications use the Mac OS X spelling dictionaries to which this document refers. Some third-party applications use their own dictionaries, and you should see third-party documentation for questions about them. Applications that use the Mac OS X spelling dictionaries have Spelling submenu choices in the Edit menu.
To change the language dictionary used by the spell check feature:
1. Open an application that uses a built-in dictionary. Mail is an example.
2. Choose Spelling from the Edit menu, and Spelling from the submenu.
3. In the Spelling dialog box, select the desired dictionary language from the pop-up menu.
4. Close the window.
Note: You must repeat these steps for other applications that use the built-in dictionaries.
