3. Word 2021 vs Word 2024

The differences in Word are mainly cosmetic and ergonomic:

• Interface: Word 2024 adopts the Fluent design with rounded corners and modernized icons
• Accessibility: a better accessibility checker in Word 2024
• Collaboration: improved co-authoring (when used with OneDrive/SharePoint)

For everyday document writing, the two versions are nearly identical in terms of features.
