Colons and semi-colons

You learn the colon for a list or explanation, and the semi-colon for two linked clauses.

How to do the test

  1. If a list or an explanation follows a complete clause, use a colon.
  2. If two complete clauses are closely linked, use a semi-colon.

A worked example

Tap the word the colon follows. You will need three things a pencil, a ruler and a rubber.

  1. What comes next is a list.
  2. A colon introduces a list or an explanation after a complete clause.
  3. The colon goes after things.
More examples

Tap the word the semi-colon follows. The sun set the sky turned red.

  1. The sentence has two main clauses that are closely linked.
  2. A semi-colon can join two such clauses instead of a full stop.
  3. The semi-colon goes after set.

Tap the word the colon follows. The shop sold only fruit apples, pears and plums.

  1. What comes next is a list.
  2. A colon introduces a list or an explanation after a complete clause.
  3. The colon goes after fruit.

Watch out

  • You use a colon where two clauses are joined, or a semi-colon before a list.

    Ask what comes next. A list or an explanation after a complete clause needs a colon. A second complete clause needs a semi-colon.

Tips

  • If you could end the first part with a full stop, a colon or a semi-colon can take its place.

Why it works

A colon follows a complete clause and introduces what comes next: a list or an explanation. A semi-colon joins two complete clauses that belong together, instead of a full stop.
