Modify Spelling & Grammar Preferences in Word for Mac

Use the macOS-specific application preferences menu to turn off the setting that ignores uppercase words.

1
Open Word Preferences

Click on 'Word' in the top macOS menu bar next to the Apple logo, then click on 'Preferences' from the dropdown list.

2
Access Proofing Tools

In the Preferences dialog box, locate the 'Authoring and Proofing Tools' section and click on 'Spelling & Grammar'.

3
Clear the Ignore Uppercase Setting

Find the checkbox labeled 'Ignore words in UPPERCASE' and uncheck it. Close the preferences window to apply this change immediately.

Frequently Asked Questions

Why does Word for Mac ignore uppercase words by default?

Word assumes that fully capitalized text typically consists of acronyms or abbreviations (like NASA or HTTP). Since these often aren't in the standard dictionary, ignoring them prevents false spelling errors from cluttering your document.

Where is the 'File > Options' menu in Word for Mac?

The macOS operating system does not use 'File > Options'. Instead, system-wide and application-specific settings are standardized under a 'Preferences' menu, accessible by clicking the application's name (e.g., Word) in the top-left menu bar.

How do I stop Word from flagging my acronyms as misspellings after changing this setting?

Once uppercase spell-checking is enabled, legitimate acronyms may be underlined in red. Simply right-click the flagged acronym and select 'Add to Dictionary' so Word recognizes it as correct in the future.
