Question details

The user needs to resolve an issue where Microsoft Word fails to automatically capitalize the first word of a new sentence after certain words.

How to Fix Microsoft Word Not Capitalizing the First Word of a Sentence

Product: Microsoft Word
Device & OS: not provided
Scenario: Typing documents where sentences follow specific words ending in a period, such as 'other', 'others', or 'God'.
Observed behavior: Microsoft Word skips capitalizing the first letter of the subsequent sentence because the preceding words have been added to the AutoCorrect exceptions list.

Before you start

Ensure you are typing a standard period followed by at least one space at the end of your sentences, as Word requires this exact punctuation to recognize the start of a new sentence.

Solution 1Recommended

Remove Affected Words from AutoCorrect Exceptions

Clear problematic words from the First Letter exceptions list to restore normal capitalization behavior in your documents.

Microsoft Word maintains an exceptions list to prevent capitalizing words immediately following common abbreviations. Occasionally, regular words get added to this list by mistake, which prevents the next sentence from capitalizing normally.

Open Word Options

Click on 'File' in the top left corner of the Microsoft Word ribbon, then select 'Options' at the bottom of the menu.

Navigate to AutoCorrect Settings

In the Word Options dialog box, click on 'Proofing' in the left pane, then click the 'AutoCorrect Options...' button on the right.

Access the Exceptions List

Ensure you are on the 'AutoCorrect' tab, then click the 'Exceptions...' button located next to the 'Capitalize first letter of sentences' checkbox.

Delete Problematic Words

Under the 'First Letter' tab, locate the affected words (e.g., 'other', 'God') in the list. Select the word and click the 'Delete' button.

Disable Automatic Additions

Uncheck the 'Automatically add words to list' option at the bottom of the window to prevent this issue from recurring, then click 'OK' on all dialog boxes to save your changes.

Remove Affected Words from AutoCorrect Exceptions

Verify Core Setting: While in the AutoCorrect menu, double-check that the 'Capitalize first letter of sentences' box is actively checked.

Solution 2

Check Formatting and Punctuation Spacing

Verify that hidden formatting marks or incorrect spacing aren't interfering with Word's ability to detect a new sentence.

Frequently Asked Questions

Why does Microsoft Word stop capitalizing after certain abbreviations?

Word's AutoCorrect feature maintains an exceptions list to prevent capitalizing words immediately following common abbreviations, such as 'etc.' or 'Dr.'. If you accidentally trigger the undo shortcut after an auto-capitalization, Word might automatically add that preceding word to the exceptions list.

How do I turn on automatic capitalization in Word?

Go to File > Options > Proofing, click on 'AutoCorrect Options', and ensure the checkbox for 'Capitalize first letter of sentences' is checked under the AutoCorrect tab.

Can I stop Word from automatically adding words to the AutoCorrect exceptions list?

Yes. Open the AutoCorrect Options, click 'Exceptions...', navigate to the 'First Letter' tab, and uncheck the box labeled 'Automatically add words to list'.

Does manual formatting affect sentence capitalization?

Yes. If you use a soft return (Shift+Enter) instead of a standard paragraph break (Enter), or if you forget to add a space after the period, Word will not recognize the text as the start of a new sentence.
