Colon or semi-colon: the same or different?

The colon (nothing to do with the bowels) is a useful little creature: 🙄   it introduces an idea or a list.   In my previous sentence, I could have got away with just using a full stop (or period, for American readers – again, no reference to anatomy intended here!)

But that seems boring and unimaginative to me: the colon keeps me interested, it tells me there’s more to come.

If I want to list several items or ideas, it helps to break up what could be a long sentence, allows me to pause for breath; :mrgreen: it helps to create a new concept, subtly highlighted above what might otherwise be a flat, boring shopping list.

Let me try to elaborate with an example: 🙄

  • “When I pack my suitcase, I try to put heavy things like my shoes, books and hairdryer at the bottom, so as not to crush the more delicate things.”

I think it sounds better this way: 🙄

  • “When I pack my suitcase, I try to plan how everything is arranged: 🙄 shoes, books and hairdryer at the bottom, delicate things at the top.”

Just a subtle difference, but a bit more stylish – in my opinion!


What’s the difference between the colon and the semi-colon then?

It may not look that much different, but I would say they are not interchangeable. The semi-colon looks like a comma with a dot above it, and this can be a good way to remember what it does: :mrgreen:   a semi-colon creates more separation between thoughts than a comma does but less than a full stop does. In short, almost anywhere you can use a full stop, you can use a semi-colon, except at the end of a sentence.

Usually the second clause (or piece of the sentence) after the semi-colon, is related to the first one, for example: 🙄

  • “She wiped a hand across her brow; :mrgreen:   the second shot had been so much closer than the first!” 

Not as clumsy as just saying a lame “because”.


You might have noticed some funny blinking faces and little green men above. 

These are just to highlight my liberal sprinklings of colons 🙄  and semi-colons :mrgreen: – surprising how often they appear isn’t it!  Dashes are quite useful too, and can be used in a similar way.

Most punctuation marks are used to enhance your writing, and it’s a good idea to learn how to use each one correctly, so as to really get your message across. And if you want a really useful tip to encourage people to read to the end of your article, throw in a redundant cumquat!
