What are Compound Nouns
A noun is a part of speech that identifies a person, place, thing or idea. Sometimes, words can be combined to form a new word. A compound noun is such a word. A compound noun is a noun that is made with two or more words. In this article, we’ll look at compound nouns, their composition, and usage.
Composition of Compound Nouns
A compound noun is a noun that is made up of two or more words. Each word of the noun adds to the meaning of the noun. A compound noun can be made of two nouns, a noun and an adjective, a noun and a verb, etc. Given below are some examples of compound nouns based on their construction.
Noun + Noun
Bus stop, football, bedroom, motorcycle
Adjective + Noun
Whiteboard, hardware, redhead
Verb + Noun
Living room, swimming pool, washing machine, driving license
Noun + Verb
Sunset, haircut, train-spotting
Verb + Preposition
Adjective + Verb
dry-cleaning, public speaking
As seen from the above examples, a compound noun is made of two words. The first word describes what kind of object or person it is, or what its purpose is. The second word identifies the object or person.
Compound nouns can be written in three ways. Some compound names are written as one word. These types of compound words are called solid or closed compound nouns.
Ex: bedroom, toothpaste, policeman, motorcycle
Sometimes compound nouns are connected by a hyphen.
Ex: mother-in-law, passer-by, runner-up
Some compound nouns appear as two separate words. These are called as open or spaced compound nouns.
Ex: water tank, bus stop, swimming pool
The difference in usage of open, hyphenated or closed compound nouns depends on different varieties of language as well as different styles of different writers.
Plural Forms of Compound Nouns
When making a compound noun plural, if the noun is considered as a single word, you can simply add a –s- to the end of the word. But if there are two or more words, you have to find the base word (most significant part of the word) and make it plural. For example,
seashell – seashells
bedroom – bedrooms
toothbrush – toothbrushes
mother-in-law – mothers-in-law
director general – directors general
Get-together – Get-togethers
