The user needs to prevent Microsoft Word from improperly breaking single words across two lines without hyphenation.

How to Fix Word Splitting Words Across Lines in Windows 10

Product: Microsoft Word
Device & OS: Windows 10
Scenario: Editing or formatting text in a Word document where automatic line breaks act abnormally.
Observed behavior: Word incorrectly splits a single word across two lines (e.g., placing 'the wh' on one line and 'ole word' on the next) without using standard hyphenation rules.

Before you start

Before altering system fonts or deep language settings, highlight the affected text and ensure there are no hidden spaces, manual line breaks, or unusual paragraph indentations inserted by mistake.

Solution 1Recommended

Configure Proofing Language and Disable Auto-Detection

Incorrect language settings can cause Word's dictionary and line-breaking algorithms to malfunction, resulting in unnatural word splitting.

Microsoft Word relies on its proofing language dictionary to know how and where to break words at the end of a line. If the language is mismatched or auto-detection gets confused, words may split abruptly.

Select the affected text

Press 'Ctrl + A' to select your entire document, or use your mouse to highlight the specific paragraphs where words are splitting incorrectly.

Open Language Settings

Navigate to the 'Review' tab on the top ribbon, click on 'Language' in the Language group, and select 'Set Proofing Language' from the drop-down menu.

Set the correct language

In the dialog box, scroll through the list and select your primary language, such as 'English (United States)'.

Disable language auto-detection

Uncheck the box at the bottom that says 'Detect language automatically', then click 'OK' to apply the changes.

Configure Proofing Language and Disable Auto-Detection

Formatting Reset: Disabling automatic detection forces Word to strictly follow standard English line-breaking rules, immediately resolving most unnatural word splits.

Solution 2

Replace a Damaged Font File

If the issue only occurs with a specific font like Times New Roman, the font file itself might be corrupted in your Windows 10 system.

Solution 3

Test Formatting in a New Document

Sometimes document-specific XML corruption causes bizarre text wrapping issues that cannot be fixed by changing global settings.

Frequently Asked Questions

Why does Word split words without adding a hyphen?

This usually happens when the document's proofing language is mismatched or set incorrectly, causing Word's built-in dictionary to fail at recognizing where natural syllable breaks occur. It can also be triggered by a corrupted font file misreporting character sizes.

Can a damaged font really cause text wrapping issues?

Yes. If a font file (like Times New Roman) is corrupted in your Windows 10 Fonts folder, Word may incorrectly calculate the width of the characters. This forces the software into making erratic line breaks and mid-word splits because it misjudges the available margin space.

How do I turn off automatic language detection in Word?

Go to the 'Review' tab on the ribbon, click 'Language', then select 'Set Proofing Language'. In the pop-up dialog box, locate and uncheck the box labeled 'Detect language automatically', then click OK.

Does clearing formatting help stop word splitting?

Yes, occasionally hidden formatting tags force unnatural text breaks. You can select the affected text and press 'Ctrl + Space' to remove manual character formatting, which frequently forces Word to revert to standard text wrapping behavior.
