Relative Clauses: Defining and Non-Defining

Introduction

Relative clauses give extra information about a noun. There are two types: defining (essential) and non-defining (non-essential). Knowing the difference is important for clear writing and communication.

1. Defining Relative Clauses

These clauses provide essential information needed to identify the noun. Without them, the sentence would be incomplete or unclear. No commas are used. Example: "The student who studies hard will succeed." "The book that I read was interesting."

Relative pronouns: who (subject – people), whom (object – people), which (things), that (people/things, informal), whose (possession).

2. Non-Defining Relative Clauses

These clauses provide extra, non-essential information. They are set off by commas. The noun is already identified or unique. Example: "My brother, who lives in London, is a doctor." "The Eiffel Tower, which is in Paris, is a famous landmark."

Relative pronouns: who, whom, which, whose (NOT "that").

Key Differences

• Defining: No commas, uses "that", essential information.
• Non-defining: Commas, no "that", extra information.

Exercises

Add commas where needed: "The woman who lives next door is kind." "My car which is red is very old."
