What are Compound Nouns and How are They Formed?

Compound nouns are words formed by combining two or more words to create a new word with a different meaning. They can be formed by joining two nouns, a noun and an adjective, a noun and a verb, or other combinations.

Types of Compound Nouns

There are three main types of compound nouns:

1. Open compound nouns: These are compound nouns that are written as separate words, such as "ice cream" or "coffee shop".
2. Hyphenated compound nouns: These are compound nouns that are written with a hyphen, such as "mother-in-law" or "self-esteem".
3. Closed compound nouns: These are compound nouns that are written as one word, such as "bedroom" or "firefighter".

Using Compound Nouns in Sentences

When using compound nouns in sentences, it is important to remember that they function as a single unit. This means that they take on the grammatical role of a single noun. For example:

1. "I bought a coffee at the coffee shop." In this sentence, "coffee shop" is a compound noun that functions as the object of the verb "bought".
2. "She has a part-time job." In this sentence, "part-time job" is a compound noun that functions as the subject complement.
3. "He is a high school student." In this sentence, "high school" is a compound noun that functions as an adjective modifying "student".
