What is a Noun as Adjective?
A noun as adjective is a noun placed directly before another noun to modify or specify it. Unlike regular adjectives, noun adjectives describe the kind, purpose, or material of the second noun. This is common in English for adding details to writing and speech.
Rules for Using a Noun as Adjective
The noun adjective usually comes before the noun it describes.
It mostly stays in the singular form (e.g., “shoe shop,” not “shoes shop”).
If the main noun is plural, the adjective noun stays singular (“book shops,” not “books shops”).
Sometimes common collocations use plural (e.g., “sports day,” “clothes shop”).
Common Examples of Noun Adjectives
- Chicken soup (soup made from chicken)
- Apple pie (pie filled with apple)
- Computer desk (desk for computers)
- Car keys (keys for a car)
- Birthday party (party for a birthday)
- Coffee mug (mug for coffee)
- Glass window (window made of glass)
- Flower garden (garden for flowers)
Compound Noun Adjectives
Compound noun adjectives combine two or more nouns, or a noun with an adjective, to describe a main noun. Usually, they are written as separate words, but sometimes as hyphenated or single words, especially as the collocation becomes common in English writing.
| Compound Noun Adjective | Main Noun | Example in a Sentence |
|---|---|---|
| Washing | Machine | I bought a new washing machine. |
| Full-time | Job | She has a full-time job. |
| Bedroom | Window | The bedroom window is open. |
| News | Anchor | The news anchor began the bulletin. |
| Horse | Race | The horse race starts at noon. |
How to Identify a Noun as Adjective in Sentences
Look for a noun that comes directly before another noun.
Ask what kind of main noun is being referred to. The describing noun tells you more: “coffee shop” is a shop for coffee.
Noun adjectives answer “what kind?”, “what type?”, or “what material?” about the main noun.
Using Noun Adjectives in Classroom and Exams
Questions may ask you to combine words to make noun adjective phrases (“school” + “bus” = “school bus”).
You may be asked to pick the correct form in MCQs, fill-in-the-blanks, or rewrite sentences with noun adjectives.
Learning the rules builds confidence and accuracy in written work and competitive tests.
