Hyphens

  • Use hyphens with compound words, e.g. twenty-seven, self-contained.
  • Hyphens are also used in compound adjectives before nouns. Compound adjectives are a combination of words which together act as an adjective. Examples: I gave them an up-to-date report. My report was up to date.
  • Hyphens are used to break a word which falls at the end of a line and continues on the next line.

📚
A self-contained person is independent and not easily influenced by others.

Add hyphens where possible:

"Major General Robert "Iron Guts" Kelly is gonna perish in a full scale, blazing, all out glorious, star spangled bannered death.”

Watch the clip and check your answer:

Answer

"Major General Robert "Iron Guts" Kelly is gonna perish in a full-scale, blazing, all-out glorious, star-spangled-bannered death.” → full-scale - using all available resources, e.g. a full-scale investigation → blazing - very bright and hot, powerful → all-out - made with maximum effort, e.g. all-out effort, all-out campaign compare: all out (adverb) e.g. We’re going all out to win. → The Star-Spangled Banner - the national anthem of the United States → spangled - covered with small sparkling objects, e.g. a spangled dress

En Dashes (Alt+0150)

En dashes are a bit longer than hyphens. They are as wide as an “n”.

  • Use en dashes when writing a range of numbers, dates, or times, e.g. 2010–2011, 11:00 a.m.⁠–⁠1:00 p.m.
You can’t use the en dash if you use “from” or “between” when introducing a range. Take a look at this incorrect example: We are open from 11:00 a.m.–1 p.m. Here are the correct versions of this sentence: We are open from 11:00 a.m. to 1 p.m. We are open 11:00 a.m.–1 p.m.
  • Use it to report scores or results of games. Example: Cal defeated USC 24–14 Friday night in Berkeley in the final game of the season for both teams.
  • Use it to show distance. Example: The New York–Prague flight is very long.
  • (Optional) Use it instead of a hyphen in a compound adjective if it consists of many words. hyphen → She is an award-winning novelist. en dash → She is a National Book Award⁠–⁠winning novelist. (example reference: link)

“Pennsylvania manhandled Kentucky”. It means that Pennsylvania completely destroyed Kentucky.

Em Dashes (Alt+0151)

Em dashes are approximately the width of an an “m”. It’s used to make a pause in a sentence. It’s stronger than a comma but weaker than a full stop. It can be used instead of commas, parenthesis and even colons. Its main aim is to add emphasis.

  • Use it instead of commas or parenthesis to emphasise some information. Examples: She went on holiday, the fourth one this year, with her new boyfriend. 🥱 She went on holiday (the fourth one this year) with her new boyfriend. 😐 She went on holiday—the fourth one this year—with her new boyfriend. 😱
What’s the difference? Commas are neutral. They introduce some additional information. 🥱 Parenthesis/the brackets show that this information is not very important. 😐 Em dashes emphasise that information. Perhaps we’re judging her. 😱
  • Use it instead of commas or parenthesis to simply clarify. Examples: Please contact my manager—John Smith—if you have any questions.
  • Use it to replace a colon to emphasise information at the end of a sentence. The sentence will look less formal. Examples: I’ll ask you only one thing: never lie to me. I’ll ask you only one thing—never lie to me.
  • Use it to replace a colon to introduce a list. The sentence will look less formal. Examples: I’ve worked with people of various nationalities: Italians, Spaniards, Brits, and Poles. I’ve worked with people of various nationalities—Italians, Spaniards, Brits, and Poles.
  • Use it to replace a semicolon to emphasise the information after the em dash. Semicolons’ job is to connect two independent clauses that are somehow related. Learn how to use a semicolon here: link. Examples: I can’t bake the cake; I don’t have the ingredients. I can’t bake the cake—I don’t have the ingredients.
  • It’s used to show a sudden change of thought. Examples: I was wondering if you could—I’m sorry. Are you busy? My plan was initially to exercise—oh my gosh, what an adorable dog!
