COMMAS & RELATIVE CLAUSES
Exercise 2: Classifying relative clauses

Purpose: This exercise helps you to understand the difference between essential and non-essential relative clauses and their effect on the use of the comma. Remember, a comma is needed to separate non-essential relative clauses from the rest of the sentence but not used with essential relative clauses.

Instructions: Read the sentences in the next exercise and decide whether each sentence includes one of the following:

  • essential relative clauses (needed to define the meaning of the word before)
  • non-essential relative clauses (providing extra information which could be omitted)
  • no relative clauses
Don't ignore the feedback. It explains the reasons why certain answers are incorrect, so make sure you read the feedback before moving on to the next question!
