A noun can modify another noun that follows it . As a modifier, the first noun gives specific information about the following noun. In nearly all cases , the noun that acts as the modifier is in singular form.

  • They do not have vegetable soup, but they do have chicken soup and tomato soup.

In the sentence, the nouns  vegetable ,  chicken  and  tomato  are modifiers. They modify  soup . Without the modifiers, we would not know what soup they have or do not have, and all we would know is they have soup.

As stated, the modifying noun is placed attributively; that is, before the noun it describes to add meaning to it (the noun being modified). For example, we know what a ship is, but do we know what type of ship it is or what it is used for? By using a noun acting as an adjective before the noun ship , we get to know what ship it is – a battleship, cargo ship, container ship, cruise ship, merchant ship, sailing ship, spaceship, or supply ship, or even an enemy ship or a pirate ship.

Examples:

  • Business/girls’/language/village school – She is a teacher in a  language school .
  • Corner/gift/pet/shoe shop – The  gift shop  offers a small selection of  leather goods .
  • Family/farm/pet/police/sheep/sniffer/toy dog – The  police dog  was sniffing round the detainee's heels.
  • Council/country/dream/farm/mansion/tree/summer house – They rented a  council house  when they got married.

Examples:

  • We are renovating the old  farm buildings . .
  • They spent the weekends doing the  flower bed .
  • She kept her  money box  under her bed.
  • The  road accident  injured five people.
  • He still keeps the  library books  after they have expired.

When a noun used as a modifier is combined with a number expression, the noun is singular and a hyphen is used.

Examples:

  • He took a  half-year  course in raising pigeons.
  • He does a  one-man  show in an open-air theatre.
  • The pilot overshot the runway and crashed his  two-seater  aircraft. .
  • She plays in a  five-girl  rock band.

Noun modifiers of noun modifiers are used together.  

Examples:

  • He sprawled on the  family room couch  reading newspaper.
  • That one over there is a  toy factory building .
  • You can get your  rock garden tools  in this store.
  • His  company car workshop  is demanding overdue payments.
  • Their two-partner computer business  is expanding fast.
  • The family lived in a  four-bedroom country house .
  • He will have to serve a  six-year prison sentence  for attempted murder.
  • The  50-acre apple orchard  attracts hordes of tourists. 

    (In the first example above, family is a noun modifier and room too is a noun modifier. This means the noun modifier family is modifying the noun modifier room . In the lower list, each example has two noun modifiers modifying one noun; for example, two-partner and computer together modify the noun business .)
