Semicolons

A semicolon ; joins two main clauses that are closely linked, where each could be a sentence on its own. It also separates the items of a long list when the items already contain commas. It was raining; we stayed inside.

Key facts

  • A semicolon joins two main clauses that are closely linked. Each could be a sentence on its own: Mia loves maths; her brother prefers art.
  • A semicolon separates list items that already contain commas: We visited Cairo, Egypt; Rome, Italy; and Paris, France.
  • After a semicolon, carry on with a small letter (unless the word is a name or I). A comma can't join two sentences: It was raining, we stayed inside. is wrong.
  • Before however or therefore joining two main clauses, use a semicolon, with a comma after the word: It rained; however, we went out.
