Adding a new language for authoring and proofing in Microsoft Office allows you to write and check spelling, grammar, and style in that language. Here's how to do it:
Step 1: Open an Office Application
You can start with any Office app like Word, Excel, or PowerPoint.
- Open Microsoft Word (or any other Office app).
 - Click on File in the top-left corner.
 - Select Options at the bottom of the left-hand menu.
 
Step 2: Access Language Settings
- In the Word Options window (or Excel/PowerPoint Options), click on Language in the left-hand pane.
 - You will see three categories: 
- Office display language
 - Office authoring languages and proofing
 - Preferred languages
 
 
Step 3: Add a New Authoring Language
- Under Office authoring languages and proofing, click Add a Language.
 - A list of available languages will appear. Scroll or search for the language you want to add.
 - Select the language and click Add.
 
Step 4: Install Proofing Tools (if needed)
- If the language you added doesn’t have proofing tools installed, Office will prompt you to download them.
 - Click Not installed next to the language, and follow the link to download the proofing tools from Microsoft’s site.
 - After installation, restart your Office apps.
 
Step 5: Set as Default (Optional)
- If you want the new language to be your default for authoring: 
- Select the language in the list.
 - Click Set as Preferred.
 
 
Step 6: Start Using the Language
- Now you can start typing in the new language.
 - Office will automatically use the correct proofing tools for spelling and grammar checks.
 
Tips
- You can switch between languages easily by changing the proofing language in the Review tab → Language → Set Proofing Language.
 - If you're using Office on Mac or the web, the steps are slightly different. Please see below:
 
Mac (Office 365 / Office 2021)
- Open Word, Excel, or PowerPoint.
 - Go to Tools → Language.
 - Select the language you want to use for proofing.
 - Click OK.
 - If the language isn’t installed, Office will prompt you to download the necessary proofing tools.
 - Restart the app after installation.
 
On Mac, the authoring language is set per document. You can change it anytime via Tools → Language.
