How Do I Set the Default Language in Pages? In Pages, you can change the default language to British English in the Inspector --> Text --> "More" tab --> Language: British English.

However, this reverts somehow in every launch of Pages. How do I set British English as the default language so that vocabulary checks are done according to British English?
You have to change the settings in the "International" panel in System Preferences.


Go to System Preferences.
Go to the Language &amp; Text (In 10.6) panel (the language tab appears first by default).
Put your preferred language at the top of the list (you might have to edit the list).


Relaunch your iWork application (Pages, Numbers, Keynote) and your preferred language will be used as default language.
