Adjective Phrase and Adjective Clause Difference

To understand the difference between adjective phrases and adjective clauses, we need to define them first.

Must Learn: Difference Between Phrase and Clause

First, look at the definition of an adjective and its function to make it easier for you to understand the difference between an adjective phrase and an adjective clause.

Difference Between Adjective Phrase and Adjective Clause

Adjective: An adjective describes things that usually appear before a noun or a pronoun in a sentence. The noun described by an adjective can be people, place, idea, or thing.

Example: Today is the longest day of this year.

The word longest in this sentence is an adjective that modifies the noun day.

Adjective Phrase: A group of words without a subject-verb combination that does the work of an adjective is called an adjective phrase.

Example: Today is the day of greatest length.

In this sentence, ‘of greatest length’ is the group of words performing the same function as a single adjective. It does not compose its own subject and predicate(verb). Therefore, it is an adjective phrase.

Adjective Clause: An adjective clause follows nouns; it provides information about the noun it follows. It has its own subject and predicate and does the work of a single adjective.

Example: I don’t remember the day when l was born.

The group of words ‘when I was born’ does the same function as the adjective and adjective phrase did in the above sentences and contains the subject I and verb was born. Therefore, this group of words is an adjective clause.

Note: Adjective clause is also known as a relative clause.

Both an adjective phrase and an adjective clause do the work of an adjective, i.e. modify a noun, and both always appear as part of a large sentence. The following table presents some key differences between adjective phrases and adjective clauses.
