Can a Word document have two languages?

If you're working with multiple languages, you can manage the list of editing languages in use in the Word Options screen. Click the Language button on the Review tab. Select Language Preferences. Here, you can see all the editing languages currently in use and add new ones quickly.

How do you serve a page with content in multiple languages?

To change the language, just simply set the lang attribute. We can define it anywhere in the document, such as in the body, in the paragraph, in the heading, or in the span tag. But the best practice is to set the lang in the span tag.
