The Semicolon

The function of a semicolon

A semicolon looks like this: ;

It is most widely used to connect two separate but closely linked clauses in one sentence. When used to combine two or more parts in one sentence, all parts are given equal status.

Semicolons, like commas, suggest a pause — longer than the one of a comma, but short of that of a full stop.

You can use a semicolon when you want to link two independent clauses together which are closely related.

For example, take the following two sentences:

  • Come to the coworking space on a Wednesday.
  • The Street Diner has a lunchtime residency then.

These sentences both function independently, but they are linked. So it would be perfectly appropriate to use a semicolon, like this:

Come to the coworking space on a Wednesday; the Street Diner has a lunchtime residency then. 

Semicolon vs colon

Semicolons are similar to colons but are not the same. The two punctuation marks are often confused, by the general public and grammarians alike. The question of their appropriateness for certain contexts is often disputed. A colon is more often used to introduce a list. For example:

  • To make a cup of tea you need the following: a kettle, water, a cup, and a teabag. 

Notice that the first clause doesn’t make sense on its own, which is why a colon is used. It also precedes a list, which is usually when colons are used.

Without the words ‘the following’, a colon wouldn’t be needed for the above sentence and a comma would be more appropriate.

Semicolons can also be used in lists, but in a different way. They tend to be used as separators in this instance, in list items already containing commas. For example:

  • She had a few favourite teachers. Rebecca, the English teacher; Mark, the History teacher; and Anna, the art teacher.

In the second sentence, the clause after the comma adds detail to the preceding clause. The semicolon separates it from the following clauses, which follow the same structure.

Semicolon vs comma

Choose a comma after the first independent clause while connecting two separate clauses to one of the following coordinating conjunctions: but, for, and, nor, or, yet, so. Take the following examples:

  • I like to sometimes use semicolons, but mostly I prefer to keep my sentences short.
  • Readable business writing tends to be short and snappy, so it’s better to start a new sentence if appropriate.

Commas are more appropriate in these examples because they precede a connective.


To see the semicolon in action, take a look at these examples:

  • “With educated people, I suppose, punctuation is a matter of rules; with me it is a matter of feeling. But I must say I have great respect for the semicolon; it’s a very useful little chap.”
    — Abraham Lincoln
  • “There are the children who make those delightful, hilarious, sometimes astonishingly grave overtures of friendship in the unpredictable fashion of children; other children, having been taught that the devil is a black man, scream in genuine anguish as I approach. Some of the older women never pass without a friendly greeting, never pass, indeed, if it seems that they will be able to engage me in conversation; other women look down or look away or rather contemptuously smirk.”
    — James Baldwin, Stranger in the Village
