Pages in wrong language

Are the menu names In Spanish or English?

Is this an example of the 'Spanish' you see? (Ignore the red bits—aimed a bit high when I took the screen shot.)

This is "placeholder text" that will disappear as soon as you start typing in the space it occupies. It's in Latin so that the person viewing it can concentrate on the appearance of 'text' in the document, without being distracted by what it says (unless that viewer reads Latin).

Are you sure it's Spanish? Has this happened before? Do you mean to say the menubar on top on the screen shows Spanish words when using Pages and English words elsewhere? I assume English is the active language throughout the OS right now?

Could it be that you chose a template that used Latin (Lorem Ipsum) as placeholder text that you simply type in to replace with your own text?
