An adjective is a word used to describe or modify a noun in a sentence. The purpose of using an adjective with the noun is to provide more information about that specific noun. However, compound adjectives are different in the sense that they are made up of two or more words, and their function is the same as simple adjectives.
In this article, you will learn what compound adjectives are, how they are formed, their usage, and examples of sentences using compound adjectives.
Compound adjectives are formed by combining two or more words that work together as a single unit to modify a noun in the sentence. These words, often linked by a hyphen, function as a single adjective in the sentence.
Examples of Compound Adjectives
- well-known
- quick-witted
- high-risk
- three-story
Formation of Compound Adjectives
Compound adjectives are formed by combining two or more words. They are easy to form and can be formed in several ways, depending on the words that help us to form compound adjectives. Let’s talk about their formation in more detail!
1. Adjective + Noun
Combining an adjective and a noun can create a compound adjective.
For example:
- high-risk
- long-term
2. Adjective + Adjective
When two adjectives are combined, they often describe a state or quality. See the following examples:
For example:
- bitter sweet
- red-hotÂ
3. Noun + Adjectives
In some cases, a noun and an adjective are used together as a compound adjective.
For example:
- world-famous
- sun-dried
4. Noun + Participle (Present /Past)
Combining a noun with a participle, either present or past, can form a descriptive compound adjective.
For example:
- heart-breaking
- home-grown
5. Adverb + Participle
An adverb combined with a participle can also create a compound adjective. These adjectives often emphasize the extent of the action.
For example:
- well-educated
- highly-regarded
Hyphenation Rules
One of the most common questions about compound adjectives is when to use a hyphen.Â
The general rule is that a hyphen is used when the compound adjective precedes the noun it modifies. In simple words, when a compound adjective comes before the noun it modifies.Â
Examples:
- a well-known artist
Here, a well-known artist uses a hyphen, but the artist is well known does not. The hyphen helps to clarify that the words work together as a single unit, thus preventing confusion in the sentence.
Exceptions to the Hyphenation Rules
However, there are exceptions. When compound adjectives follow the noun that it is modifying in the sentence, the hyphen is usually dropped. Additionally, some compound adjectives, especially those formed with adverbs ending in -ly, do not require a hyphen at all.Â
Examples:
- a highly skilled worker
Types of Compound Adjectives
Compound adjectives can be divided into two types based on their structure and function. Let’s find out each type in more detail!
1. Based On Structure
Compound adjectives are further subdivided into three types based on their structure:
- Closed Form
- Hyphenated Form
- Open Form
Closed Form
In some cases, compound djectives are written as a single word without a hyphen.
Examples:
- bookmarked page
Here, the word bookmarked is a closed form compound adjective.
Hyphenated Form
The most common form of compound adjectives is the hyphenated form in which two or more words are connected by a hyphen.
Examples:
- high-speedÂ
Open Form
Some compound adjectives are written as two separate words without a hyphen, especially when used in certain contexts.Â
Examples:
- high school teacher
Here, the words high school are used adjectively.
2. Based on Function
Compound adjectives are further divided into two groups based on their function:
- Descriptive Compound Adjectives
- Numerical Compound Adjectives
Descriptive Compound Adjectives
These adjectives provide additional information about a noun.Â
Examples:
- fat-growing industry
- bright-eyed child
Descriptive Compound Adjectives
These adjectives often involve numbers in their formation. They help us describe quantity, time, or distance.Â
Examples:
- two-hour meeting
- three-story building
Common Usage Scenarios
Compound adjectives are frequently used in English. Here are some of the common scenarios of their usage:
Compound adjectives are frequently used to describe characteristics.
Example
- blue-eyed girl
- broad-shouldered man
Here, blue-eyed and broad-shouldered are compound adjectives.
When describing someone’s traits or abilities, compound adjectives add depth and precision.Â
Example
- well-spoken presenter
- Quick-witted comedian
Compound adjectives help us to express situations where time, distance, or quantity needs to be expressed.
Example
- two-hour meeting
- three-story building
Compound adjectives are often used in literature and poetry. They help us to create vivid imagery and rhythm.
Example
- dark-eyed stranger
- long-lost love
Compound Adjectives vs. Other Adjectives
A simple adjective provides a basic description of the noun it modifies. A compound adjective provides a more specific and nuanced meaning in the sentence. For example, red is a simple adjective, but blood-red is a compound adjective that conveys a deeper and more intense color.
It is essential to understand the difference between compound nouns and compound adjectives.Â
A compound noun is a noun made up of two or more words that function as a single unit. For example;
- toothpaste
- bus stop
On the other hand, a compound adjective modifies a noun. For example;
- high-speed train
One common mistake is misplacing the hyphen or using it incorrectly. For example, writing two hour meeting instead of two-hour meeting can lead to confusion.
Therefore, you should always remember to hyphenate when the compound adjective comes before the noun, and drop the hyphen when it follows.
Examples of Compound Adjectives Used in Sentences
- She is a well-known author.
- We took a long-term approach to the problem.
- He wore a brightly-colored shirt.
- He is a quick-witted man.
Conclusion
Compound adjectives are a combination of words that modify nouns in the sentences. They are used to convey complex ideas with precision and clarity. Therefore, learning how to form them and when to use a hyphen can help you improve your writing and communication skills.Â
