In my editing of fiction manuscripts, I often find writers using ellipses (...) where they should use dashes, or hyphens instead of dashes, etc. Here's a brief run-down on the use of these punctuation marks.
A. Ellipsis (…) or Dash (—)?
An ellipsis (…) is used to show hesitation:
“What I meant is… I don’t know how to begin…”
or a trailing off:
"She came with you? But I thought..." She paused.
"You thought what? Come on, spit it out."
(Also, usually in nonfiction, indicates the omission of words in a quoted text.)
A dash (—), also called em dash, is used to show an interruption in speech:
“But nothing! I don’t want to hear your excuses!”
or a sudden break in thought or sentence structure: “Will he—can he—find out the truth?”
The dash is used for amplifying or explaining, for setting off information within a sentence, kind of like parentheses or commas can do:
“My friends—I mean, my former friends—ganged up on me.”
B. Hyphen vs. En Dash vs. Em Dash:
The en dash is longer than a hyphen but shorter than an em dash (the normal dash).
A hyphen (-) is used within a word. It separates the parts of a compound word: bare-handed, close-up, die-hard, half-baked, jet-lagged, low-key, never-ending, no-brainer, pitch-dark, self-control, single-handed, sweet-talk, user-friendly, up-to-date, watered-down, work-in-progress, etc.
Dashes are used between words.
An en dash (–) connects numbers (and sometimes words), usually in a range, meaning “to”: 1989–2007; Chapters 16–18; the score was 31–24 for Green Bay; the London–Paris train; 10:00 a.m.–2:00 p.m.
An em dash (—) is used to mark an interruption, as mentioned above (“What the—”), or material set off parenthetically from the main point—like this. Don’t confuse it with a hyphen (-). In fiction, the em dash almost always appears with no spaces around it. Some authors, publishers, and companies prefer an en dash with spaces on each side of it for this: ( – ).
C. How to Create Em Dashes and En Dashes:
Em dash (—) Ctrl+Alt+minus (far top right, on the number pad). CMS uses no spaces around em dashes; AP puts spaces on each side of em-dashes
En dash (–) Ctrl+minus (far top right, on the number pad)
D. Advanced Uses of the Dash (Em Dash):
According to the Chicago Manual of Style (6.87), “To avoid confusion, no sentence should contain more than two em dashes; if more than two elements need to be set off, use parentheses.”
Also, per CMS, “if an em dash is used at the end of quoted material to indicate an interruption, a comma should be used before the words that identify the speaker:
“I assure you, we shall never—,” Sylvia began, but Mark cut her short.
But: “I didn’t—”
No comma after it here, as that’s the end of the sentence, and no tagline.
The Chicago Manual of Style also says (6.90) that if the break belongs to the surrounding sentence rather than to the quoted material, the em dashes must appear outside the quotation marks: “Someday he’s going to hit one of those long shots and”—his voice turned huffy—“I won’t be there to see it.”
Using an em dash in combination with other punctuation: CMS 6.92: “A question mark or an exclamation point—but never a comma, a colon, or a semicolon, and rarely a period—may precede an em dash.
All at once Jeremy—was he out of his mind?—shook his fist in the officer’s face.
Only if—heaven forbid!—you lose your passport should you call home.
