When to Use an Em Dash
The em dash is a versatile punctuation mark that can replace commas, parentheses, or colons—all depending on context. It's typically used without spaces on either side in American English, though some style guides prefer spaces.
Common uses:
- Setting off a parenthetical phrase—like this one—within a sentence
- Indicating an abrupt break in thought or speech
- Emphasizing a conclusion or explanation
