Understanding Relative Clauses in English

Relative clauses are an essential component of English grammar, allowing speakers to provide additional information about nouns in a sentence. This page outlines the different types of relative pronouns and their usage in both necessary (defining) and non-necessary (non-defining) relative clauses.

Definition: A relative clause is a subordinate clause that modifies a noun or pronoun in the main clause.

The page presents a table that categorizes relative pronouns based on their function in the clause (subject, object, possessive, or other complements) and whether they refer to people or things. This classification helps in choosing the appropriate relative pronoun for different contexts.

Example: "The boy who is crossing the street is my brother." (Defining relative clause) Example: "John, who is crossing the street, is my brother." (Non-defining relative clause)

For necessary (defining) relative clauses referring to people, the table shows:

• Subject: WHO
• Object: WHO/WHOM
• Possessive: WHOSE
• Other complements: PREPOSITION + WHOM

For necessary (defining) relative clauses referring to things:

• Subject: WHICH
• Object: WHICH
• Possessive: WHOSE
• Other complements: PREPOSITION + WHICH

Vocabulary: Defining relative clauses (also known as restrictive relative clauses) are essential to the meaning of the sentence and are not set off by commas.

For non-necessary (non-defining) relative clauses referring to people, the options are:

• Subject: WHO
• Object: WHOM
• Possessive: WHOSE
• Other complements: PREPOSITION + WHOM

For non-necessary (non-defining) relative clauses referring to things:

• Subject: WHICH
• Object: WHICH
• Possessive: WHOSE
• Other complements: PREPOSITION + WHICH

Vocabulary: Non-defining relative clauses (also known as non-restrictive relative clauses) provide additional, non-essential information and are set off by commas.

This comprehensive overview helps learners understand the nuances of using relative pronouns in different contexts, enabling them to construct more sophisticated and grammatically correct sentences in English.

Highlight: The choice of relative pronoun depends on whether it refers to people or things, and its function within the relative clause.
