How to Fix OneNote Proofing Language Changing to Spanish

Product: Microsoft OneNote
Device & OS: Windows
Scenario: Typing English text in OneNote with a Spanish keyboard installed on the system.
Observed behavior: OneNote automatically changes the proofing language to Spanish, marking correctly spelled English words as incorrect.

Before you start

Ensure you have saved your current OneNote notebooks and check your Windows taskbar to see which keyboard layout is currently active before adjusting language settings.

Solution 1Recommended

Manually Set Proofing Language and Toggle Keyboard Layouts

This is the best method if you need to keep both English and Spanish keyboards installed on your system.

Switch to English Keyboard Layout

Press the Windows key + Spacebar to toggle through your installed keyboards until the English keyboard layout is active before typing in OneNote.

Select the Affected Text

Highlight the text in your OneNote page that is currently being incorrectly marked with Spanish proofing red underlines.

Change Proofing Language

Navigate to the 'Review' tab on the ribbon, click 'Language', and select 'Set Proofing Language'. Choose 'English' from the list and click 'OK'.

Frequently Asked Questions

Why does OneNote keep changing my proofing language?

OneNote automatically detects the active Windows keyboard layout. If a Spanish keyboard is active in your system tray, OneNote assumes you are typing in Spanish and switches the proofing dictionary accordingly.

Can I disable automatic language detection in OneNote?

Unlike Microsoft Word, OneNote does not have a straightforward 'Detect language automatically' checkbox in its proofing settings. It relies heavily on your Windows input language settings, which is why manual adjustment is often required.

How do I quickly switch between English and Spanish keyboards in Windows?

You can rapidly toggle between installed keyboard layouts by pressing the Windows Key + Spacebar or by using the Alt + Shift keyboard shortcut.
