Compound Nouns are an indispensable grammar topic in everyday English writing and communication. In fact, they have become so common that you may not even realize that some of the vocabulary you use every day are compound nouns.
So what are English compound nouns? How can you form and apply compound nouns most accurately in the IELTS test? Let's find out with IDP through the article below!
1. What Are Compound Nouns?
Compound nouns are nouns made up of two or more words that come together to refer to a specific person, place, object, or idea. These individual words may not always be nouns themselves. Compound nouns are used frequently in both writing and conversation.
There are three types of compound nouns in English:
Common nouns: fish sticks, hairdresser, e-commerce
Proper nouns: Whitehouse, New York, Pizza Hut
Abstract nouns: shopaholic, obsessive-compulsive disorder

2. Types of Compound Nouns in English
Compound nouns can be classified into three main categories based on spelling and pronunciation:
Type | Description | Examples |
---|---|---|
Open compounds | Two or more separate words used together | hot dog, bus stop, swimming pool |
Hyphenated compounds | Words connected by hyphens | mother-in-law, merry-go-round, self-confidence |
Closed compounds | Words joined into one word | rainfall, keyboard, snowball |
3. Common Structures of Compound Nouns
Compound nouns can be formed by combining different word types:
Structure | Examples |
---|---|
Noun + Noun | boyfriend, bus station, bookstore |
Noun + Verb | sunrise, haircut, earthquake |
Noun + Adjective | software, greenhouse, Snow White |
Noun + Prepositional Phrase | sister-in-law, passer-by, voice-over |
Verb + Preposition | lookout, make-up, sign in |
Verb + Noun | washing machine, breakfast, stepmother |
Preposition + Noun | underworld, underwear, onlooker |
Adjective + Noun | high school, hot dog, flashlight |
4. Plural Forms of Compound Nouns
When changing compound nouns to plural form, the main noun is usually the word made plural:
son-in-law → sons-in-law
swimsuit → swimsuits
If there is no clear main word, pluralize the last element:
apple tree → apple trees
grown-up → grown-ups

5. Stress Rules for Compound Nouns
Stress patterns can change the meaning of a word, making stress placement essential in English communication.
For two-word compound nouns, stress typically falls on the first word:
WHITE house = the official residence of the president
white HOUSE = a house painted white
While this rule covers most compound nouns, there are exceptions. Learning and practicing vocabulary frequently will help you internalize correct pronunciation.
Examples:
SWIMsuit
PLAStic bag
