What are Compound Nouns with Adjective + Noun?
A compound noun is a noun made from two or more words. When you combine an adjective with a noun, you create a compound noun. The adjective describes or modifies the noun, and together they form one single idea. For example: "high school" is a compound noun. "High" is an adjective that describes what type of school it is. The two words work together to create a meaning that is different from each word alone.
How to Form Adjective + Noun Compounds
The structure is simple: adjective + noun = compound noun. You write the adjective first, then the noun. Usually, you write them as two separate words. Some compound nouns can be written as one word or with a hyphen, but most adjective + noun compounds are written as two words. The adjective does not change form. You use the same adjective whether the noun is singular or plural.
Important Rules
Remember: the adjective stays the same for both singular and plural nouns. For example, you say "a black cat" and "three black cats" – not "blacks cats". Also, the stress and meaning come from how the two words combine. "Dark chocolate" means chocolate that is dark, not just any chocolate. Learning common adjective + noun compounds will help you speak and write more naturally.

What to Remember
- A compound noun combines an adjective and a noun to create a single idea with new meaning.
- Always write the adjective before the noun when forming compound nouns.
- The adjective describes or modifies the noun in the compound structure.
- Compound nouns like "high school" have meanings different from their individual words.
- Treat adjective + noun compounds as one unit, not two separate words.
