To bolden an unreadable PDF segment that has been pasted into a Word document, you can try the following methods:

1. Select the Text: Highlight the unreadable text in Word.
2. Use Keyboard Shortcut: Press Ctrl + B (Windows) or Command + B (Mac) to apply bold formatting.
3. Change Font Style: If the text remains unreadable, consider changing the font to a different one that supports bold formatting better.
4. Adjust Character Style: Use a character style like “Strong” in Word to ensure you’re applying a true bold weight rather than faux bold.
5. Recreate the Segment: If the text is still not clear, you may need to manually retype it using a bold font.
6. If these methods do not improve readability, consider using PDF editing software to enhance the text directly before pasting it into Word.
