Fascinating Fact:

Appositives are extra naming clauses and need commas, My sister, a keen sprinter, ran 200 metres in 31 seconds.

In KS3 English, commas help readers follow your meaning. Use them to separate a fronted clause, to bracket off nonessential information, and to mark appositives that rename a noun.

  • Appositive: Extra information that renames a noun, usually set off with commas, as in my brother, Tom.
  • Subordinate clause: A clause that cannot stand alone. If it comes first, add a comma after it.
  • Nonrestrictive clause: Information that is not essential to the meaning. Place commas around it.
When do I use a comma before which or who?

Use a comma with nonrestrictive clauses, for example, The bike, which I fixed, is fast. Do not use a comma if the clause is essential.

Do I need a comma after a fronted subordinate clause?

Yes, usually. For example, When the bell rang, we lined up. If the clause follows the main clause, a comma is often not needed.

What is an appositive and where do the commas go?

An appositive renames a noun. Place commas around it if it is extra, as in Mrs Khan, our teacher, smiled. If it is essential, omit commas.
