dashes, hyphens
Dashes, also called em dashes ( — ), can serve several functions. They signal abrupt change, set off a series within a phrase, mark attribution in pull quotes and start lists. Use a space on both sides of a dash in body copy, and use a space after a dash for attribution in pull quotes.
For example:
Howling Cow ice cream flavors — especially Cherry Brick Road and Tuffy’s Toffee — show off our school spirit.
“I’ve always dreamed of playing baseball for NC State.”
— Mr. Wuf
Hyphens ( – ) act as joiners, such as in compound modifiers: first-generation college student. Hyphens are also used in ranges: 8-9 a.m., Jan. 1-4. There are no spaces surrounding a hyphen.
