Fascinating Fact:

A relative clause adds extra information about a noun. The bus that stops at Gate B arrives at 8,10 am.

In KS3 English, you’ll learn to use relative clauses to add precise information without starting a new sentence. You’ll practise choosing who, which, that and punctuating clauses so ideas flow smoothly.

  • Relative pronoun: A word like who, which, that introducing a clause about a noun.
  • Defining clause: Essential information that identifies the noun; no commas needed.
  • Non-defining clause: Extra information; use commas to separate it from the main clause.
What is a relative clause in KS3 English?

A relative clause is a group of words beginning with a relative pronoun (who, which, that) that gives more information about a noun in the sentence.

When do I use commas with relative clauses?

Use commas for non-defining clauses: “My bike, which is red, is fast.” Do not use commas for defining clauses: “The bike that is red is mine.”

What’s the difference between who, which and that?

Who is for people, which for things/animals, and that is common in defining clauses for people or things. Avoid that after commas.
