Quotes and Quotations
Follow these rules when using quotes and quotation marks:
The period and the comma always go inside the quotation marks.
Right: She told us “stay in school,” which was good advice.
Right: He said, “I’m going to the store.”
Wrong: He said, “I’m going to the store”.
The dash, the exclamation point and the question mark go inside the quotation marks when they apply to the quote only. When they apply to the whole sentence, they go outside the marks.
Right: Sgt. Carter gave the following order: “Peel potatoes — then lights out!”
Right: Gomer Pyle said, “Golly, Sergeant!” when he heard the news.
Right: Francis Schaeffer’s book asks, “How Shall We Then Live?”
Right: What did Martin Luther King Jr. mean when he said, “I have a dream”?
Note: This usage prevails in the United States. United Kingdom and Canada apply different rules. The colon and semicolon should be placed outside quotation marks. When text ending with one of these punctuation marks is quoted, the colon or semicolon is dropped.
Right: The president said the plan needed “a few minor adjustments”; however, he did not reject it entirely.
In running quotations, each new paragraph should begin with open quotation marks (no closing marks). Only the final paragraph should contain the closing quotation mark.
Right: The speech was as follows: “Welcome, ladies and gentlemen. I have a few points to make today. The first is to thank you for this honor. My accomplishments are noteworthy only in so far as they help to advance this important field of human endeavor.
“The second is to ask you to continue thinking about this critical issue. Only through continued research and experimental programs such as the one you’ve recognized today will we advance our cause and improve our society.
“Finally, let me ask you to do more than turn your mental energies to this important effort. Give your total energies — in the form of financial support, volunteer time, active advocacy — for the sake of progress. Then we can all share in this special honor. Thank you.”
When including a quote or “highlighted” word inside another quotation, use single quotes (‘) instead of double (“).
Right: In his charge to the committee, the chair said, “I have often told you, ‘don’t give up the ship.’ Thanks to your efforts, we’ve been able to reach our goal.”
Right: The chair said, “I have often told you, ‘don’t give up the ship.’”
Spacing at End of Sentence
Use a single space at the end of a sentence and after a colon. Double spaces date back to the days of typewriters, when all characters were allotted the same amount of space. Computerized typesetting adjusts the spacing for a good fit. Extra spaces create gaps and look unprofessional.
