What punctuation goes before a dialogue tag?

Use a comma before a lowercase dialogue tag when the quoted words form a statement: “I know the way,” she said. Preserve a question mark or exclamation mark when the line is a question or exclamation.

What is the difference between an action beat and a dialogue tag?

A dialogue tag identifies speech with a verb such as said or asked. An action beat is a separate sentence describing what the character does, so it follows a period rather than a comma.

When should fiction writers use an em dash in dialogue?

Use an em dash when a speaker is interrupted or cuts off mid-thought. Use an ellipsis when the speaker trails off, hesitates, or leaves the thought unfinished without an interruption.

Dialogue Punctuation Rules: Definition and Examples | EpicScribe

Dialogue punctuation is the system of commas, periods, quotation marks, em dashes, and ellipses that shows how spoken lines relate to tags and action beats.

Why It Matters in Creative Writing

Correct punctuation makes a conversation easy to follow without calling attention to itself. In fiction, the punctuation also communicates interruption, hesitation, emphasis, and the boundary between what a character says and what they do.

Examples

Dialogue tag: “I know the way,” she said. A lowercase dialogue tag is grammatically attached to the quoted sentence with a comma.
Action beat: “I know the way.” She opened the map. Opening a map is an action, not a speaking verb, so it starts a new sentence with a period.
Interruption: “I was just going to—” “Leave.” An em dash shows that another speaker cuts the line off. An ellipsis shows the first speaker trailing away.

Practical Editing Tips

Use a comma before a lowercase tag such as “said” or “asked,” but a period before a separate action beat.
Start a new paragraph every time the speaker changes, even in a fast exchange.
Use em dashes for interruption and ellipses for trailing off; choose the mark that matches the performance you want.
