Mastering Non restrictive Relative Clauses

Learn to use non-restrictive relative clauses to add extra details to sentences without changing their main meaning.

Non-restrictive Relative Clauses allow you to add non-essential information to a sentence, enhancing detail without changing the main meaning. This lesson will guide you in recognizing and using non-restrictive clauses effectively.

Examples

Example 1

My car, which I bought last year, is already having problems.

The clause "which I bought last year" adds extra information about the car without altering the main point.

Example 2

Our professor, who has written several books, is an expert in medieval history.

The clause "who has written several books" provides additional information about the professor.

How It Works

Meaning

Non-restrictive relative clauses add extra information to a sentence without altering its core meaning. They are typically set off by commas and provide additional details about a noun.

These clauses use relative pronouns like who, which, or whose and are crucial at the B2 level for enhancing writing sophistication.

Use it when

  • Adding non-essential information about a noun.
  • Writing formal or academic texts where detail is important.
  • Clarifying a point without changing the main message.
  • Enhancing narrative or descriptive writing.
