I have previously covered how to use an en dash (–) and an em dash (—). Now to turn to the thing they are not: a hyphen.

A hyphen (-) shows that the matter it is attached to is not a complete word by itself. It should not be used with a space at both ends, although sometimes it is appropriate for it to have a space at one end.

The use of hyphens is often a matter of style. But they are used to do the following things:

  • join compound words
  • join compound modifiers
  • attach prefixes
  • indicate a piece of a word
  • indicate a word break at the end of a line

You might have heard of soft hyphens and hard hyphens. Soft hyphens are those that indicate word division at the end of a line. Hard hyphens are those that indicate words or parts of words are joined together to form compounds. There’s no difference in size or shape.

Hyphens are also used to indicate stammering or paused speech:

'W-w-what are we to do?'

And they indicate the omission of the second part of a hyphenated expression or solid compound:

three- and five-door cars
over- and underpaid employees

If you would like to find out more about when to use a hyphen, I can recommend the Penguin Guide to Punctuation for a thorough and simple explanation.

    • Ah, I hate to be the bearer of bad news but, no, they are unlikely to be the same button. I think the combination of keys you need will depend on the keyboard and operating system, but I’ve got the alt key code down to a muscle memory now.
      Thank you very much! 🙂
