Definition of Adjective Clauses and Phrases
Adjective clauses and phrases are grammatical structures that function as adjectives, providing descriptive information about nouns or pronouns in a sentence. While they both serve the same purpose, they differ in their structure and complexity.
Understanding these differences is key to using them correctly and effectively.
What is an Adjective Clause?
An adjective clause is a dependent clause that modifies a noun or pronoun. It contains a subject and a verb and is introduced by a relative pronoun (who, whom, which, that) or a relative adverb (where, when, why). The adjective clause provides additional information about the noun or pronoun it modifies, adding detail and specificity to the sentence.
For example, in the sentence “The book that I borrowed from the library is very interesting,” the clause “that I borrowed from the library” is an adjective clause modifying the noun “book.” It tells us which book is being referred to.
What is an Adjective Phrase?
An adjective phrase is a group of words that modifies a noun or pronoun, functioning as an adjective. Unlike an adjective clause, it does not contain a subject and a verb. Adjective phrases can take various forms, including prepositional phrases, participle phrases, and infinitive phrases.
For example, in the sentence “The girl with the red hair is my sister,” the phrase “with the red hair” is an adjective phrase modifying the noun “girl.” It describes which girl is being referred to.
Function and Context
Both adjective clauses and phrases serve to provide additional information and description. They add depth and detail to sentences, making them more informative and engaging.
The choice between using a clause or a phrase often depends on the level of detail required and the desired style of writing. Clauses offer more complexity and can convey more information, while phrases are more concise and can streamline sentences.
Consider these examples:
- Adjective Clause: The house that stands on the hill is very old.
- Adjective Phrase: The house on the hill is very old.
Both sentences convey similar information, but the adjective clause provides a slightly more detailed description.
Structural Breakdown
Understanding the structure of adjective clauses and phrases is essential for using them correctly. Each type has its own specific components and patterns that you need to be aware of.
Adjective Clause Structure
The basic structure of an adjective clause includes a relative pronoun or relative adverb, followed by a subject and a verb. The relative pronoun or adverb connects the clause to the noun or pronoun it modifies, known as the antecedent.
Structure: Antecedent + Relative Pronoun/Adverb + Subject + Verb (+ Object/Complement)
Example: The man who lives next door is a doctor.
- Antecedent: The man
- Relative Pronoun: who
- Subject: who (also functions as the subject of the clause)
- Verb: lives
Adjective Phrase Structure
Adjective phrases are more varied in their structure, depending on the type of phrase. However, they all share the characteristic of not containing a subject and a verb.
Prepositional Phrase: Preposition + Noun Phrase
Example: The book on the table is mine.
Participle Phrase: Participle (present or past) + Object/Complement
Example: The dog, wagging its tail, greeted me.
Infinitive Phrase: To + Verb (+ Object/Complement)
Example: The best way to learn English is through practice.
Types and Categories
Adjective clauses and phrases can be categorized based on the specific words or structures they employ. Understanding these categories will help you identify and use them effectively.
Relative Pronouns
Relative pronouns introduce adjective clauses and connect them to the antecedent. The most common relative pronouns are who, whom, which, and that. The choice of relative pronoun depends on the antecedent and its function within the clause.
- Who: Refers to people (subject)
- Whom: Refers to people (object)
- Which: Refers to things or animals
- That: Refers to people, things, or animals
Example: The woman who is speaking is my teacher.
Relative Adverbs
Relative adverbs also introduce adjective clauses, but they refer to time, place, or reason. The most common relative adverbs are where, when, and why.
- Where: Refers to a place
- When: Refers to a time
- Why: Refers to a reason
Example: The restaurant where we met is now closed.
Participle Phrases
Participle phrases are adjective phrases that begin with a present participle (-ing form) or a past participle (-ed form for regular verbs, irregular form for irregular verbs). They modify the noun or pronoun by describing an action or state.
Example: The book, written by a famous author, is a bestseller.
Prepositional Phrases
Prepositional phrases consist of a preposition followed by a noun phrase. They function as adjectives by providing information about location, time, or other relationships.
Example: The car in the garage is mine.
Infinitive Phrases
Infinitive phrases begin with to + base form of the verb. They can function as adjectives by describing the purpose or characteristic of a noun.
Example: The best way to learn is by doing.

Usage Rules
Proper usage of adjective clauses and phrases requires adherence to specific rules regarding punctuation, essential vs. non-essential clauses, and reduction techniques.
Punctuation Rules
The punctuation of adjective clauses depends on whether the clause is essential (restrictive) or non-essential (non-restrictive). Essential clauses are necessary to identify the noun they modify, while non-essential clauses provide additional information that is not crucial to the sentence’s meaning.
- Essential Clauses: Do not use commas.
- Non-Essential Clauses: Use commas to set off the clause from the rest of the sentence.
Example:
- Essential: The student who studies hard will succeed. (No commas because the clause identifies which student)
- Non-Essential: My sister, who lives in London, is a doctor. (Commas because the clause provides extra information about my sister)
Essential vs. Non-Essential Clauses
Determining whether a clause is essential or non-essential is crucial for correct punctuation. Ask yourself: Is the information in the clause necessary to identify the noun it modifies?
If yes, it’s essential; if no, it’s non-essential.
Essential Clauses are also known as restrictive clauses. They are vital to the meaning of the sentence and cannot be removed without changing the core information. They are not set off by commas.
Non-Essential Clauses, also known as non-restrictive clauses, add extra information that is not critical to understanding the sentence. They can be removed without altering the main meaning and are always set off by commas.
Consider these examples:
- Essential: The book that I borrowed from you is missing.
- Non-Essential: The book, which is a first edition, is very valuable.
Reduction Rules for Adjective Clauses
Adjective clauses can sometimes be reduced to adjective phrases to create more concise sentences. This is typically done by removing the relative pronoun and verb “to be.”
Rule 1: If the relative pronoun is the subject of the clause and the verb is “to be,” you can remove both.
Example:
- Original: The man who is sitting over there is my father.
- Reduced: The man sitting over there is my father.
Rule 2: You can also reduce adjective clauses using prepositional phrases.
Example:
- Original: The house which is on the hill is very old.
- Reduced: The house on the hill is very old.
Common Mistakes
Learners often make common mistakes when using adjective clauses and phrases. Being aware of these errors can help you avoid them.
| Incorrect | Correct | Explanation |
|---|---|---|
| The book, that I borrowed, is good. | The book that I borrowed is good. | “That” should not be used with commas in essential clauses. |
| The woman who’s car is red is my neighbor. | The woman whose car is red is my neighbor. | “Whose” is the possessive form of “who.” |
| The city where I live, is beautiful. | The city where I live is beautiful. | Commas should not be used in essential clauses. |
| The boy whom is tall is my friend. | The boy who is tall is my friend. | “Who” should be used as the subject of the clause. |
| The reason why I am late, is because of the traffic. | The reason I am late is because of the traffic. | Avoid redundant phrasing with “the reason why” and “because.” |
| The car which I bought it is new. | The car which I bought is new. | Do not repeat the subject of the main clause in the adjective clause. |
