What Are Compound Nouns?
Compound nouns are words formed by combining two or more smaller words into a single unit. These new words function as nouns, naming people, places, things, or ideas.
For instance, instead of saying "sun" and "rise," we can combine them to form the compound noun "sunrise."
Types of Compound Nouns
There are three main types of compound nouns:
1- Closed Compound Nouns
These words are written as one unit, with no spaces or hyphens separating the individual words.
Examples include:
doorknob
toothpaste
homework
2- Hyphenated Compound Nouns
These nouns use hyphens to connect the component words.
Examples include:
mother-in-law
well-being
high-rise
3- Open Compound Nouns
These consist of separate words that, together, function as a single noun.
Examples include:
post office
web design
ice cream
Formation of Compound Nouns
Compound nouns can be formed in various ways, often combining different parts of speech:
Noun + Noun
This is the most common type, where two nouns come together to create a new noun.
For instance:
bookstore (book + store)
football (foot + ball)
classroom (class + room)
Adjective + Noun
An adjective can combine with a noun to create a compound noun.
Examples include:
weekend (week + end)
bedroom (bed + room)
high school (high + school)
Verb + Noun
Sometimes, a verb and a noun join forces to form a compound noun.
Examples include:
download (down + load)
handshake (hand + shake)
sunset (set + sun)
