Definition of Relative Pronouns

A relative pronoun is a type of pronoun that introduces a relative clause. A relative clause is a dependent clause that modifies a noun or pronoun in the main clause. These clauses provide additional information about the noun or pronoun they modify, helping to specify or describe it further. Relative pronouns act as a bridge, connecting the relative clause to the noun or pronoun it refers to, which is called the antecedent.

Relative pronouns serve two key functions: they act as pronouns within the relative clause (replacing a noun or pronoun) and they connect the relative clause to the main clause. This dual role allows for the creation of more complex and detailed sentences. Without relative pronouns, we would need to use multiple simple sentences to convey the same information, making our writing less fluent and more repetitive.

Consider the following example: “The book is on the table. I bought the book yesterday.” Using a relative pronoun, we can combine these two sentences into one: “The book that I bought yesterday is on the table.” Here, “that” is the relative pronoun, “I bought yesterday” is the relative clause, and “book” is the antecedent.

Structural Breakdown

The basic structure involving relative pronouns is as follows:

Main Clause + Relative Pronoun + Relative Clause

The relative pronoun replaces a noun or pronoun within the relative clause. This replacement allows the relative clause to seamlessly integrate with the main clause. The antecedent, the noun or pronoun that the relative pronoun refers to, is usually located immediately before the relative pronoun.

For example, in the sentence “The woman who lives next door is a doctor,” the main clause is “The woman is a doctor,” the relative pronoun is “who,” and the relative clause is “who lives next door.” The antecedent is “woman.” The relative pronoun “who” replaces “the woman” in the relative clause, effectively combining the two clauses into a single, more informative sentence.

Understanding this structure is crucial for correctly identifying and using relative pronouns. Recognizing the main clause, the relative clause, the relative pronoun, and the antecedent will help you construct grammatically sound and meaningful sentences.

Types of Relative Pronouns

There are five main relative pronouns in English: who, whom, whose, which, and that. Each pronoun has specific uses and restrictions, depending on the type of noun or pronoun it refers to and the function it serves within the relative clause.

Who

Who is used to refer to people when the relative pronoun is the subject of the relative clause. It is used in both restrictive and non-restrictive clauses.

Example: “The student who studies diligently will succeed.” Here, “who” refers to “the student” and acts as the subject of the verb “studies.”

Whom

Whom is used to refer to people when the relative pronoun is the object of the verb or a preposition in the relative clause. While less common in informal speech, it is still important for formal writing and grammatical accuracy.

Example: “The author whom I admire has written several bestsellers.” Here, “whom” refers to “the author” and is the object of the verb “admire.”

Whose

Whose is used to show possession or ownership, referring to both people and things. It indicates that the noun or pronoun in the relative clause belongs to the antecedent.

Example: “The car whose engine is broken is in the shop.” Here, “whose” refers to “the car” and indicates that the engine belongs to the car.

Which

Which is used to refer to animals and things. It is used in both restrictive and non-restrictive clauses, but in restrictive clauses, “that” is often preferred. “Which” is always used in non-restrictive clauses.

Example: “The book which I borrowed from the library is very interesting.” Here, “which” refers to “the book.”

That

That is used to refer to people, animals, and things. However, it is primarily used in restrictive clauses. It is often interchangeable with “who” or “which” in restrictive clauses, but it cannot be used in non-restrictive clauses.

Example: “The movie that we watched last night was fantastic.” Here, “that” refers to “the movie.”

Usage Rules for Relative Pronouns

Using relative pronouns correctly involves understanding their specific roles and the types of clauses they introduce. Key considerations include distinguishing between restrictive and non-restrictive clauses, knowing when relative pronouns can be omitted, and understanding how they interact with prepositions.

Restrictive vs. Non-Restrictive Clauses

Restrictive clauses (also called essential clauses) are necessary to identify the noun or pronoun they modify. They provide essential information that limits or defines the antecedent. These clauses are not set off by commas.

Example: “The book that I borrowed from the library is overdue.” The clause “that I borrowed from the library” is essential to identify which book is overdue.

Non-restrictive clauses (also called non-essential clauses) provide additional information about the noun or pronoun but are not essential for identifying it. They add extra detail that can be removed without changing the basic meaning of the sentence. These clauses are set off by commas.

Example: “My sister, who lives in New York, is a lawyer.” The clause “who lives in New York” provides additional information about the sister but is not necessary to identify her.

The choice of relative pronoun can also be influenced by whether the clause is restrictive or non-restrictive. “That” is generally used only in restrictive clauses, while “which” is used in non-restrictive clauses. “Who” and “whom” can be used in both types of clauses.

Omitting Relative Pronouns

In certain situations, the relative pronoun can be omitted, particularly in restrictive clauses where the relative pronoun is the object of the verb. This omission often makes the sentence sound more natural and less formal.

Example: “The book I read was fascinating.” Here, “that” can be omitted: “The book that I read was fascinating” becomes “The book I read was fascinating.”

However, you cannot omit the relative pronoun if it is the subject of the relative clause. For example, in the sentence “The student who studies hard will succeed,” you cannot omit “who.”

Relative Pronouns with Prepositions

Prepositions can be used with relative pronouns in two main ways:

1. Formal Style: The preposition precedes the relative pronoun, typically “whom” or “which.”
2. Informal Style: The preposition is placed at the end of the relative clause.

Formal example: “The person to whom I spoke was very helpful.”

Informal example: “The person who I spoke to was very helpful.”

In formal writing, it is generally preferred to place the preposition before the relative pronoun. However, in informal speech and writing, it is more common to place the preposition at the end of the clause. When “that” is used as a relative pronoun, the preposition always comes at the end of the clause. You cannot say “To that I spoke.”

Common Mistakes with Relative Pronouns

One of the most common mistakes is using “which” instead of “who” or “whom” to refer to people. “Which” should only be used for animals and things.

Incorrect: The teacher which is grading papers is very dedicated.

Correct: The teacher who is grading papers is very dedicated.

Another common mistake is using “that” in non-restrictive clauses. “That” should only be used in restrictive clauses.

Incorrect: My sister, that lives in New York, is a lawyer.

Correct: My sister, who lives in New York, is a lawyer.

A further error involves confusion between “whose” and “who’s.” “Whose” is a relative pronoun indicating possession, while “who’s” is a contraction of “who is” or “who has.”

Incorrect: The student who’s essay won the prize is very talented.

Correct: The student whose essay won the prize is very talented.

Another frequent mistake is omitting the relative pronoun when it is the subject of the clause.

Incorrect: The man helped me was very kind.

Correct: The man who helped me was very kind.
