Non-defining relative clauses - B2 Advanced Grammar English A1-C2 Study Notes

Overview

Non-defining relative clauses are a pivotal component of English grammar, especially at the B2 Advanced level. Unlike defining relative clauses, which are essential to the meaning of a sentence, non-defining relative clauses provide additional information that can be omitted without altering the fundamental meaning. These clauses are often set off by commas and are used to give extra details about a noun. Understanding non-defining relative clauses is crucial for fluency in complex sentence structures, enhancing both spoken and written communication skills, which are vital for advanced English learners. While defining relative clauses help to specify which person or thing we are talking about, non-defining clauses add supplementary context. For instance, in the sentence "My brother, who lives in London, is visiting us next week," the information about living in London is supplementary. These clauses can be used to convey opinions, facts, or background information in a more sophisticated manner, making them particularly useful in formal writing and elaborate conversations. Students progressing from beginner to proficiency should focus not just on identifying these clauses but also on their correct punctuation and placement in various contexts.
