Is it better to use brackets inside of a parentheses when including an abbreviation?

You should not use brackets inside parentheses when including an abbreviation. Brackets are used for different purposes within parentheses:

* Clarification: Brackets can be used within parentheses to provide additional information or clarification, such as a definition or explanation. For example: "(The company's CEO [Chief Executive Officer] will be speaking at the conference)."

* Interjections: Brackets can be used to indicate an interjection or a comment that is not part of the main sentence. For example: "(He said, 'I'm going to the store [to buy milk].')"

Abbreviating within parentheses:

The best practice is to simply place the abbreviation directly within the parentheses, without any additional punctuation:

* Correct: "(e.g.,)"

* Incorrect: "(e.g.[for example])"

Example:

Instead of:

"(The meeting will be held on [Thurs. [Thursday]] at 10:00 AM.)"

Write:

"(The meeting will be held on Thursday at 10:00 AM.)"
