This tutorial shows how to change the proofing language for comments in Word.
But first, why would you want to change the proofing language for comments? Because …
Comments in Word Inherit Proofing Languages
When you use Word’s Track Changes to edit someone else’s document, the comment tool automatically inherits the original author’s proofing language along with spelling and grammar-check settings. Normally this inheritance isn’t a problem. However, if the author wrote the text in another language and then translated it to English, your comments may be ignored by the spelling and grammar check (now called the Editor) until you change the comments to your desired proofing language.
Please note that the images below are from Word for Office 365, which is currently the same as Word 2019. The steps are the same for Word 2016 and Word 2013; however, the interface in these older versions may look slightly different.
