Adjective clauses, also known as relative clauses, are a fundamental aspect of English grammar. They provide more information about a noun in a sentence, making your writing more precise and engaging. Understanding how to use adjective clauses can significantly enhance your language skills, allowing you to construct more complex and informative sentences. In this article, we will delve into the definition of adjective clauses, explore their structure, and examine various examples to help you grasp their usage effectively.
What is an Adjective Clause?
An adjective clause is a group of words that contains a subject and a verb and functions as an adjective. It provides additional information about a noun or pronoun in a sentence. Adjective clauses are introduced by relative pronouns such as “who,” “whom,” “whose,” “that,” and “which,” or by relative adverbs such as “when,” “where,” and “why.”
Adjective clauses are essential because they allow writers and speakers to add detail and specificity to their descriptions. For example, consider the following sentence: “The man is my neighbor.” This sentence is straightforward but lacks detail. By adding an adjective clause, we can make the sentence more informative: “The man who lives next door is my neighbor.”
Relative Pronouns and Adjective Clauses
Relative pronouns play a crucial role in forming adjective clauses. Here is a list of common relative pronouns and their functions:
– **Who**: Refers to people and serves as the subject of the clause.
Example: “The teacher who taught me in high school is retiring.”
– **Whom**: Refers to people and serves as the object of the clause.
Example: “The student whom the teacher praised is very diligent.”
– **Whose**: Indicates possession and can refer to people, animals, or things.
Example: “The author whose book won the award is giving a lecture.”
– **That**: Refers to people, animals, or things and can serve as the subject or object of the clause.
Example: “The car that I bought last year is very reliable.”
– **Which**: Refers to animals or things and can serve as the subject or object of the clause.
Example: “The movie which we watched last night was thrilling.”
Relative Adverbs and Adjective Clauses
Relative adverbs are used to introduce adjective clauses that provide information about time, place, or reason. Here are some examples:
– **When**: Refers to a time.
Example: “The year when we graduated was unforgettable.”
– **Where**: Refers to a place.
Example: “The house where I grew up has been renovated.”
– **Why**: Refers to a reason.
Example: “The reason why she left the job remains a mystery.”
Types of Adjective Clauses
Adjective clauses can be categorized into two types: restrictive (or defining) and non-restrictive (or non-defining) clauses. Understanding the difference between these two types is essential for proper punctuation and sentence structure.
Restrictive Adjective Clauses
Restrictive adjective clauses provide essential information about the noun they modify. Without this information, the meaning of the sentence would be incomplete or unclear. Restrictive clauses are not set off by commas.
Example: “The book that you lent me is fascinating.”
In this sentence, the clause “that you lent me” is essential to specify which book is being referred to. Without this clause, the sentence “The book is fascinating” would be too vague.
Non-Restrictive Adjective Clauses
Non-restrictive adjective clauses provide additional, non-essential information about the noun they modify. The sentence would still be complete and make sense without this clause. Non-restrictive clauses are set off by commas.
Example: “My brother, who lives in New York, is visiting us next week.”
In this sentence, the clause “who lives in New York” provides extra information about “my brother.” However, the sentence “My brother is visiting us next week” would still be complete and understandable without the clause.
Forming Adjective Clauses
To form an adjective clause, follow these steps:
1. **Identify the Noun to Modify**: Determine which noun in the sentence needs additional information.
2. **Choose the Appropriate Relative Pronoun or Adverb**: Select the correct relative pronoun (who, whom, whose, that, which) or adverb (when, where, why) based on the noun and the function of the clause.
3. **Construct the Clause**: Ensure the clause contains a subject and a verb and place it immediately after the noun it modifies.
4. **Punctuate Correctly**: Determine whether the clause is restrictive or non-restrictive and punctuate accordingly with or without commas.
Let’s look at an example:
1. **Identify the Noun to Modify**: “The woman”
2. **Choose the Appropriate Relative Pronoun**: “who” (since “woman” is a person and the clause will provide essential information)
3. **Construct the Clause**: “who works at the library”
4. **Punctuate Correctly**: Since this is a restrictive clause, no commas are needed.
Complete sentence: “The woman who works at the library is very helpful.”
Examples of Adjective Clauses in Sentences
To better understand how adjective clauses function, let’s examine several examples:
1. **The cake that she baked was delicious.**
– “that she baked” is a restrictive adjective clause modifying “cake.”
2. **The city where I was born is famous for its architecture.**
– “where I was born” is a restrictive adjective clause modifying “city.”
3. **My cousin, who is a talented musician, will perform at the concert.**
– “who is a talented musician” is a non-restrictive adjective clause modifying “my cousin.”
4. **The reason why he left early is still unknown.**
– “why he left early” is a restrictive adjective clause modifying “reason.”
5. **The house, which was built in the 19th century, is now a museum.**
– “which was built in the 19th century” is a non-restrictive adjective clause modifying “house.”
Common Mistakes to Avoid
Using adjective clauses can be tricky, and learners often make mistakes. Here are some common errors and tips to avoid them:
Misplacing the Adjective Clause
An adjective clause should be placed immediately after the noun it modifies. Misplacing the clause can lead to confusion.
Incorrect: “The book is on the table that you gave me.”
Correct: “The book that you gave me is on the table.”
Using the Wrong Relative Pronoun
Choosing the incorrect relative pronoun can alter the meaning of the sentence. Make sure to use the appropriate pronoun based on the noun and the function of the clause.
Incorrect: “The person which called you is my friend.”
Correct: “The person who called you is my friend.”
Confusing Restrictive and Non-Restrictive Clauses
Confusing restrictive and non-restrictive clauses can affect the clarity of your sentence. Remember to use commas for non-restrictive clauses and avoid them for restrictive clauses.
Incorrect: “My sister who lives in California is visiting.”
Correct: “My sister, who lives in California, is visiting.”
Incorrect: “The car, that I bought last year, is very reliable.”
Correct: “The car that I bought last year is very reliable.”
Practice Exercises
To solidify your understanding of adjective clauses, try the following exercises:
1. Identify the adjective clause in the following sentence and determine if it is restrictive or non-restrictive:

– “The man is very kind.”
3. Correct the errors in the following sentence:

3. “The laptop that I borrowed from my friend is not working.”
