Do you speak more than one language? Microsoft Office 2013 supports the use of multiple languages in proofing, writing, and spell-check. Setting it up hasn’t changed much since Office 2010, so this shouldn’t take long to walk through.
In any Office app, open the File ribbon.
From the File menu click the Options button.
In the Options window click the Language tab.
Use the drop-down menu titled “Add additional editing languages” to select the language you prefer and then click Add.
That’s it! It’s added. You can now use your newly added editing language to spell check for words written in that language.
Keep in mind that there’s a good chance your language won’t be supported as usually only English and Spanish are the defaults. If this is the case you’ll need to download and install the Office 2013 Preview Language Pack.
