Many people can't tell the difference between the hyphen (-), the en-dash (¨C), and the em-dash (¡ª). They may look similar but they can all help ensure that your writing looks professional and is easy to read. As an overview:

  • Hyphens improve clarity: there is a big difference between "a man-eating shark" and "a man eating shark".
  • En-dashes and em-dashes share a lot of the same functionality ¨C including allowing for explanations and examples to be shared, and separating clauses ¨C however, they are not interchangeable and their use is often down to personal preference.?

Let's explore what these three different dashes do and how they could improve your writing.?

Understanding hyphens: the basics

Hyphens (-) are the shortest of the three marks, and we use them to connect words that work together to express one idea (also known as "compound adjectives").

A compound adjective is a word like "part-time". We talk about ?"part-time work" and "full-time work": it would be meaningless to talk about just "time work". So, where the other word is essential to express the idea ¨C also called "modifying the word" ¨C they need to be joined with a hyphen.?

Hyphens also add clarity. My friend Joanne owns a small business but if I told you that she is a "small business owner", you might assume that Joanne is both small and happens to own a business. A hyphen comes to the rescue: if I tell you that "Joanne is a small-business owner" then there is no ambiguity.?

To summarize:?we use hyphens to join words that modify another word. In this example, the word "student" is being modified: "She is a 14-year-old student." But, we don't need the hyphen when the subject is isn't being modified: "The student is 14 years old." Other examples:

  • "This is fat-free yogurt" vs. "This yogurt is fat free"
  • "I own a one-third share of the company" vs. "One third of the company is mine"
  • "She lives in a four-storey house" vs. "Her house has four storeys"

What's an En-Dash?

The en-dash (¨C ) is slightly longer than a hyphen (and you've probably already noticed that it has a hyphen in its name). They have several uses:

Expressing a range or connection

En-dashes can replace words like "between", "to" and "through":

  • The meeting is scheduled for 10:00¨C11:00 a.m.
  • The offer is valid April¨CSeptember.?
  • We examined data from 2014¨C2024.?

For joining two nouns

Use an en-dash to connect two nouns that don't modify each other. For example:

  • The London¨CAmsterdam train
  • The blood¨Cbrain barrier
  • The U.K.¨CIndia trade talks

For digressions, clarifications and to separate clauses

En-dashes can be used like commas, colons or parentheses to help you expand upon and explain your writing. They can be used to present extra information, like examples, explanations and facts. For example:

  • We visited many states ¨C including Michigan, Indiana and Ohio ¨C while we were in America.
  • Her idea ¨C although not perfect ¨C worked well enough.
  • The discovery of penicillin ¨C a complete accident ¨C transformed medicine.
  • The Renaissance ¨C a period of history and cultural shift that marked Europe's transition from the Middle Ages to modernity ?¨C took place in the 15th and 16th centuries.?

Use the en-dash sparingly in these contexts as overuse can break your reader's concentration and make your writing harder to read. Note also that the en-dash is used with spaces here.?

Quick fun fact: the en-dash got its name because it's the length of an "n" in traditional typesetting.

Exploring the Em-Dash

The em-dash (¡ª) is the longest of the three and, yes, it's the length of an "m" in traditional typesetting.?

Like en-dashes, em-dashes can also function as commas, colons and parenthesis in presenting additional information.?Many people prefer the look of em-dashes here: note?that em-dashes are typically used without spaces around them. There's no right or wrong here, it's purely personal preference.?

However, unlike en-dashes, em-dashes are not commonly used to express ranges or connect nouns.?

The most important thing is, whether you choose to use an en-dash or an em-dash, do so consistently.

Test your knowledge

Now you know about hyphens and dashes, try these questions.?

Which sentence is correct?:

  1. He baked an egg free cake.
  2. He baked an egg ¨C free cake.?
  3. He baked an egg-free cake.

It's sentence 3. A "free cake" doesn't make sense, so we need to connect "egg-free" with a hyphen.?Now try these sentences and see if you can figure out which one is right:

  1. My dog is nine years old ¨C he's adorable.
  2. My dog is nine-years old - he's adorable.
  3. My dog is nine-years-old ¨C he's adorable.

The correct answer is 1. We don't need any hyphens here as the idea is separate from the subject of the sentence. Note the difference between this and "My five-year-old dog, where we do need a hyphen. Also note that "he's adorable" should be preceeded by an en-dash, not a hyphen ¨C an em-dash would also be acceptable here.

Finally, decide how we should describe a student who is studying modern art:

  1. She is a modern art student.?
  2. She is a modern¨Cart student. ?
  3. She is a modern-art student. ?

Here, the right answer is 3. Note that, without the hyphen, "She is a modern art student" tells us that she is up-to-date and is studying art: the hyphen is essential for clarity.

Hopefully you feel more confident in using hyphens and dashes in your writing ¨C those little marks can have a big impact on your writing. Look out for the next post in this series, where we¡¯ll explore other grammar mysteries and common grammar mistakes, and how to avoid them.

    As the new school year begins, teachers have an opportunity to set the tone for inclusion, belonging and respect. With the right strategies and activities, you can ensure every student feels seen, heard and valued from the very first day. Embracing diversity isn¡¯t just morally essential: it¡¯s a proven pathway to deeper learning, greater engagement and a more equitable society (Gay, 2018).

    Research consistently shows that inclusive classrooms foster higher academic achievement, improved social skills and increased self-esteem for all students (Banks, 2015). When students feel safe and respected, they are more likely to take risks, collaborate and reach their full potential.

    5 myths about online language learning

    By Steffanie Zazulak
    Reading time: 3 minutes

    Technology has radically changed the way people are able to access information and learn. As a result, there are a great number of tools to facilitate online language learning ¨C an area that¡¯s been the subject of many myths. Here we highlight (and debunk) some of the bigger ones¡­

    Myth #1: You will learn more quickly

    Although online learning tools are designed to provide ways to teach and support the learner, they won¡¯t provide you with a shortcut to proficiency or bypass any of the key stages of learning.?Although you may well be absorbing lots of vocabulary and grammar rules while studying in isolation, this isn¡¯t a replacement for an environment in which you can immerse yourself in the language with English speakers. Such settings help you improve your speaking and listening skills and increase precision, because the key is to find opportunities to practise both ¨C widening your use of the language rather than simply building up your knowledge of it.

    Myth #2: It replaces learning in the classroom

    With big data and AI increasingly providing a more accurate idea of their level, as well as a quantifiable idea of how much they need to learn to advance to the next level of proficiency, classroom learning is vital for supplementing classroom learning. And with the Global Scale of English providing an accurate measurement of progress, students can personalise their learning and decide how they¡¯re going to divide their time between classroom learning and private study.

    Myth #3: It can¡¯t be incorporated into classroom learning

    There are a huge number of ways that students and teachers can use the Internet in the classroom. Meanwhile, ÃÛÌÒapp¡¯s online courses and apps have a positive, measurable impact on your learning outcomes.

    Myth #4:?You can't learn in the workplace

    Online language learning is ideally suited to the workplace and we must create the need to use the language and opportunities to practise it. A job offers one of the most effective learning environments: where communication is key and you¡¯re frequently exposed to specialized vocabulary. Online language learning tools can flexibly support your busy schedule.

    Myth #5: Online language learning is impersonal and isolating

    A common misconception is that online language learning is a solitary journey, lacking the personal connection and support found in traditional classrooms. In reality, today¡¯s digital platforms are designed to foster community and real interaction. With features like live virtual classrooms, discussion forums and instant feedback, learners can connect with peers and educators around the world, building skills together.
