Do not use quotation marks for indirect quotations—those that do not relay someone’s exact words.

Do not use quotation marks just to emphasize particular words or phrases.

Do not use quotation marks around slang or colloquial language; they create the impression that you are apologizing for using those words. Instead, try to express the idea in formal language. If you have a good reason to use a slang or colloquial term, use it without quotation marks.
