Hyphens and dashes are basic to stylish writing in English. Even if your readers aren't quite sure of the precise rules that govern their use, their reading will be easier and their comprehension aided by your systematic use of these punctuation marks. The Manual of Style clearly sets out how to use all three punctuation symbols: hyphens (-), en dashes (–) and em dashes (—). If these three symbols are hard to distinguish visually (- – —), you may need to change your font or browser to a standard one that renders them properly.
If you're unsure how to key in en and em dashes, please see this.
Here, we present texts in which hyphens and/or dashes may be either wrongly used or wrongly absent; in other words, some of the examples are wrong, and some are right. Remember, it's mostly a matter of:
Em dashes are a quite separate beast, and much easier to use. Many writers don't use them at all; they use spaced en dashes – like this – instead of unspaced em dashes—like this—for their "interrupters". It's up to you.
The exercises: unfolding design. Each exercise below will present you with a portion of text in which you can correct the (mis)usage of hyphens and dashes. They are designed to be done in your head, without typing. Each one unfolds in stages that you control: first, the problem text, then a hint to help you along; then a solution; and finally an explanation.
Feedback is welcome on the talk page. For each exercise, decide on the answer in your mind before clicking on the solution. You may find this video on hyphens and dashes useful in conjunction with the exercises.
Self-help writing tutorials:
Lady Featherstone-Morley carelessly ashed her cigarette on the butanol sample.
So would an en dash (Lady Featherstone–Morley): there's no opposition or particular relationship between the names here, other than their coming together into someone's compound name.
An em dash (Lady Featherstone—Morley) would look really awkward.
The hyphen is incorrect. Here, there's a year range, requiring an en dash, which stands for "to":
During the period 2005–07,...From 2005–07, house prices in Capetown rose by a third.
The example is incorrect; this is what you need:
There were two problems:
The en dashes are required, but their formatting is incorrect; as interruptors, they must be spaced. The alternative is unspaced em dashes, like this:
Five classes—comprising more than 100 students—will compete against each other to win a prize for the best Wikipedia article on a suburb of Seattle.The example is incorrect: there should be no hyphen where a unit abbreviation is used.
The 16-kilometre (10 mi) distance between the centres has been a major impediment to economic development.Please memorise: "No hyphen after "-ly".
Why? you might ask. Because an "-ly" word, as an adverb, always qualifies a verb (an action), so your readers will already be expecting it to be joined grammatically to the next word. It's not rocket science. This is one of the most common hyphen glitches on Wikipedia.July 1870 – 10 May
