Non-Defining Relative Clause

Point 1: A defining clause acts like an adjective to describe something.

  2. I have an uncle who repairs watches.
Point 2: A non-defining clause gives extra information.
  1. She has a nice house, which was just built.
  2. We went to dinner with Jeff, whom I think you met before.
Point 3: A non-defining clause uses commas to separate the clause from the rest of the sentence.
  1. My friend, whom you met before, is coming to the party.
  2. We study Arabic, which is very hard to learn.
Point 4: A non-defining clause uses the relative pronoun "which" for things or ideas.
  1. My school, which just opened, does not have many students.
  2. He quit his job, which surprised us all.
Point 5: For people, use "who" when the modified word is the subject of the clause. Use "whom" when it is the object.
