A clause used to join two sentences together, or to provide more information about something.

Remember to use Who for people and Which for things. That can be used for both.

Using the relative clause that to combine sentences:

  • I bought a new winter coat. It is very warm.

becomes

  • I bought a new winter coat that is very warm.

Using the relative clause which to provide more information about something:

  • I live in Los Angeles. Los Angeles has lots of sunshine.

Everyone knows where LA is, so the relative clause provides more information:

  • I live in Los Angeles, which has lots of sunshine.

Using who as a defining relative clause:

  • I am looking for my brother. He is good at fixing things.

becomes:

  • I am looking for my brother who is good at fixing things
