It is quite likely that you know many compound nouns and use them every day, perhaps even without knowing! But, just what are compound nouns?
I’m a native English speaker, and even I didn’t know what they were until I started to teach English, so, let us take a look.
When two separate words are joined and form a new word that is a noun, it becomes a compound noun. (Compound, the meaning of this word is to join two or more things into one.)
Look carefully at our very first sentence of this post, can you find a compound noun we used there? If you said, without, you are correct, well done! It contains the words with and out.

Below are some of the most common compound nouns, their independent forms, and examples of how to use the compound noun. It is not a complete list by no means.

Spaced Compound Nouns
Compound nouns are a controversial part of the English language. Some compound nouns are not joined into one word but just placed in a particular word order. If misused within a sentence these words do not typically go together.
- I am going to catch the bus at the Bus Stop.
- It is going to be a Full Moon tonight.
- I have swimming lessons at the local Swimming Pool.
- We collect rain water in our Water Tank.
- You have many beautiful fish in your Fish Tank.
- I was so sick last night I thought I was going to throw up what I had eaten earlier.
Hyphenated Compound Nouns
Hyphenations are another way of creating compound nouns.
- We need to pick up our dry-cleaning before they close tonight.
- My —in-law is coming to visit us next week.
- While I park the car can you please look after the check-in at the Hotel reception desk.
