relative clause

A student underlines a relative clause in a grammar textbook.

Definition

Noun: A relative clause is a type of dependent clause that modifies a noun or noun phrase. It is typically introduced by a relative pronoun (such as who, whom, whose, which, or that) or a relative adverb (such as when, where, or why). The clause provides additional information about the noun it follows.

Usage

A relative clause functions as an adjective within a sentence. It cannot stand alone as a complete sentence and is attached to a main clause. * There are two main types: 1. Defining (or Restrictive) Relative Clause: This clause provides essential information to identify the noun it modifies. It is not separated by commas. 2. Non-defining (or Non-restrictive) Relative Clause: This clause provides extra, non-essential information about the noun. It is separated by commas.

Examples
  • Defining Relative Clause:
    • The book that you recommended was excellent. (The clause "that you recommended" specifies which book.)
    • I know a person who can help us. (The clause "who can help us" defines what kind of person.)
  • Non-defining Relative Clause:
    • My brother, who lives in Paris, is visiting next week. (The clause "who lives in Paris" adds extra information; "my brother" is already identified.)
    • The Eiffel Tower, which is in Paris, is a famous landmark. (The clause "which is in Paris" adds extra information.)
Advanced Usage
  • Relative clauses with prepositions: The relative pronoun can be the object of a preposition.
    • The house in which I grew up has been sold. (Formal)
    • The house that I grew up in has been sold. (Less formal)
    • The house I grew up in has been sold. (Informal, where the relative pronoun is omitted)
  • Reduced Relative Clauses: When the relative pronoun is the subject of the clause, it can sometimes be omitted, and the verb can be changed to a present participle (-ing form) or past participle.
    • The people who are waiting outside are getting impatient.The people waiting outside are getting impatient.
    • The car that was damaged in the accident was towed away.The car damaged in the accident was towed away.
