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

3. Common Structures of Compound Nouns

  • Compound nouns can be formed by combining different word types:

4. Plural Forms of Compound Nouns

When changing compound nouns to plural form, the main noun is usually the word made plural:

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.
