In a Word document, if you encounter punctuation word wrapping or starting a new line, it is usually caused by the "Chinese Layout" setting. In Chinese typography, punctuation marks are usually not placed at the beginning or end of a line. If you wish to change this typography behavior, you can fix it by adjusting Word's typography settings. Here's how to do it:
Open your word document.
Click on the "File" menu in the top left corner.
Select "Options" in the sidebar to open the Word Options dialog box.
In the Word Options dialog box, select the "Advanced" option.
Under the "Advanced" option, scroll down to the "Typography" section.
Look for "Chinese Typography Control" or similarly named options.
Uncheck options such as "Prohibit single punctuation marks at the beginning of the line" or "Do not display Chinese punctuation at the beginning of the line".
Click "OK" to save the settings.
After you've changed your settings, go back to your document to see if the layout of the punctuation has changed.
Make manual adjustments to specific paragraphs in the document if needed.
Menu and option names may vary slightly depending on the Word version, so please adjust them accordingly according to your specific version.
Some Word versions may not have a direct "Chinese Layout Control" option, in which case more detailed typographical adjustments may be required.
If you are using a non-Chinese version of Word, these settings may be in different places or presented in different ways.
With the above steps, you should be able to solve the problem of punctuation word wrapping in word. If the problem persists, you may need to check other settings for your document or consider using a different text processing software.
