Word is likely switching the keyboard because the document language is Spanish and the automatic keyboard-matching feature is enabled.
Use these steps:
- In Word, open File > Options > Advanced.
- Under Editing options, clear Automatically switch keyboard to match language of surrounding text.
- This setting can cause the keyboard language to change while typing.
If Word is also auto-detecting language and contributing to the behavior:
- Go to Review > Language > Set Proofing Language.
- Clear Detect language automatically.
- Automatic language detection can identify surrounding Spanish text and apply that language behavior.
If Spanish still appears as an available keyboard/input option in Windows, verify that only the English keyboard is installed:
- In Windows 11, go to Start > Settings > Time & language > Language & region.
- Select the language that contains the keyboard to keep, then select Options.
- Under keyboards, confirm only the English keyboard is present. If needed, use Add a keyboard only for the keyboard layout that should remain available.
If the language bar is visible and keyboard layouts are still switching manually, note that Alt+Shift switches keyboard layouts. Also, the Language bar appears only after two or more keyboard layouts are enabled.
