Quotation Marks
Periods, commas, question marks and exclamation points go inside the quotation marks.
Example:
Billy Collins stood in line to vote and looked up when someone asked why he came out to vote early, “I haven’t voted in 30 years and now I’m here.” he said.
Use a comma before the quotation.
Example:
New Orleans Mayor LaToya Cantrell warned residents about the dangerous hurricane heading their way. She said, “This is not a drill.”
The first letter of the first word in a quote is capitalized.
Example:
N.B.A. star LeBron James and other prominent black athletes and entertainers started a group aimed at protecting African American voting rights and encouraging people to vote.
“Yes, we want you to go out and vote, but we’re also going to give you the tutorial,” Mr. James said. “We’re going to give you the background of how to vote and what they’re trying to do, the other side, to stop you from voting.”
