Apparently a lot of people get dialogue punctuation wrong despite having an otherwise solid grasp of grammar, possibly because they’re used to writing essays rather than prose. I don’t wanna be the asshole who complains about writing errors and then doesn’t offer to help, so here are the basics summarized as simply as I could manage on my phone (“dialogue tag” just refers to phrases like “he said,” “she whispered,” “they asked”):
“For most dialogue, use a comma after the sentence and don’t capitalize the next word after the quotation mark,” she said.
“But what if you’re using a question mark rather than a period?” they asked.
“When using a dialogue tag, you never capitalize the word after the quotation mark unless it’s a proper noun!” she snapped.
“When breaking up a single sentence with a dialogue tag,” she said, “use commas.”
“This is a single sentence,” she said. “Now, this is a second stand-alone sentence, so there’s no comma after ‘she said.’”
“There’s no dialogue tag after this sentence, so end it with a period rather than a comma.” She frowned, suddenly concerned that the entire post was as unasked for as it was sanctimonious.
