How to Proof Foreign Text in Word 2013
Select the text written in a foreign language.
Drag your cursor across the text to select the text.
Click the Language button on the Review tab.
Then click Set Proofing Language from the pop-up menu to display the Language dialog box.
In the Language dialog box, choose the Spanish (Mexico) item.
You could choose another variation on Spanish, or choose French.
With your text marked as being in a foreign tongue, Word not only tries to spell-check it in English, but it spell-checks the text in that foreign tongue! So if you write lápizes instead of lápices, Word can fix it for you.
