Here's the correct way:
* Single set of quotation marks: "This is the quote," she said.
Here's why it's important:
* Clarity: Using two quotation marks in a row would be confusing. It would make it unclear where the quote starts and ends.
* Standard practice: The standard way to quote speech is with a single set of quotation marks.
Example:
* Incorrect: "This is a "quote" about using quotation marks."
* Correct: "This is a quote about using quotation marks."
