Do punctuation marks go inside or outside quotation marks? It depends.

Commas and periods go inside the quotes, whether they are part of the quoted material or not:

Franklin Roosevelt said, “We have nothing to fear but fear itself.”

“I’m looking forward to the conference,” she said.

The best picture Oscar went to “The Shape of Water.”

(Side note: In the second example, note that the quotation ends in a comma, not a period. That’s because the quoted matter is not at the end of the sentence.)

Question marks and exclamation points go inside the quotes if they are part of the quoted material – outside if they aren’t.

“Look out!” cried Chicken Little. “Can’t you see the sky is falling?”

Have you read “How to Win Friends and Influence People”?

Colons and semicolons go outside.

The following actors appear in “Mary Poppins Returns”: Emily Blunt, Lin-Manuel Miranda, Ben Whishaw and Emily Mortimer.

My favorite TV show is “Seinfeld”; unfortunately, it ended 20 years ago.
