1. Emphasis:
* If the bolded portion is a complete sentence: Punctuate it as a complete sentence.
* Example: The Earth is a sphere.
* If the bolded portion is a phrase or clause within a sentence: Punctuate it as usual, but do not add any extra punctuation around the bolding.
* Example: The Earth is a sphere that orbits the sun.
2. Title:
* If the bolded portion is a title: Punctuate it according to title capitalization rules (usually the first word and proper nouns are capitalized).
* Example: The Hitchhiker's Guide to the Galaxy is a funny science fiction novel.
* If the title is already punctuated: Do not add extra punctuation around the bolding.
* Example: She read "The Hitchhiker's Guide to the Galaxy" for the first time.
3. Highlighting:
* If the bolding is used to highlight a word or phrase: Punctuate the sentence as usual, but do not add extra punctuation around the bolding.
* Example: The planet we live on is called Earth.
General Rules:
* Avoid overusing bolding. Too much bolding can make your writing difficult to read.
* Use bolding sparingly. It is most effective when used to emphasize key points or to make important information stand out.
Example of Wrong Punctuation:
* Incorrect: The Earth is a sphere,
* Correct: The Earth is a sphere.
Example of Correct Punctuation:
* The Earth is a sphere.
* The Earth is a sphere.
Remember: The most important thing is to be consistent and to choose punctuation that makes your writing clear and easy to understand.
