When I mark my students’ writing I divide common mistakes into categories, and this ‘Nouns as adjectives’ section was getting longer and longer.
I couldn’t work out exactly what was causing the errors, so I did some research.
The more I researched, the more confused I got with all the terminology, but in this lesson, I will try to clarify the rules and give you ONE quick tip that will fix (almost) everything!
Most of the time, these language items are so common and familiar that you don’t need to think about the rules e.g. toothpaste, football, town centre, car park, dog food, shoe shop.
But sometimes they cause problems, as you can see below.
To get more information, you can google:
- nouns that act like adjectives
- noun-like adjectives
- nouns as adjectives
- attributive nouns
- noun modifiers
- adjectival nouns
- compound nouns
Also see my previous lesson relating to hyphens in compound nouns.

So what is the simple tip?
When you use nouns as adjectives, don’t put ‘s’ on the noun before the noun!
The ‘normal’ adjective rules are very simple.
Adjectives describe nouns, for example
- a nice day
- beautiful weather
- a hot cup of tea
- a sunny beach
But nouns describe nouns too.
Unlike normal adjectives, these ‘nouns as adjectives’ can go:
BEFORE the noun e.g. heart disease
AFTER the noun (with a preposition) e.g. disease OF the heart
Like ‘normal’ adjectives, these ‘noun-like adjectives’ do not need any kind of ‘s’ (plural or possessive).
A soup made of carrots = carrot soup
carrots soup carrot’s soup carrots’ soup
A park for cars = a car park
a cars park a car’s park a cars’ park
Prepositions: ‘in’ ‘of’ and ‘for’
Let’s look at the 3 most common prepositions that ‘create’ noun-like adjectives ‘in’ ‘of’ and ‘for’.

Measurements and materials
We saw examples of measurements in my previous blog about hyphens e.g.
- over 10 years = over a 10-year period
- A journey which takes 3 hours = a 3-hour journey
- An essay of 250 words = a 250-word essay
- He’s 4 years old./ He’s a 4-year-old boy.
- This house has 2 bedrooms./ This is a 2-bedroom house.
Time nouns after ‘a/an’ need ‘s’ – an hour’s delay, a moment’s hesitation
- 3 days’ wait/ a 3-day wait
The examples relating to materials are well-known e.g
- a cube made of ice = ice cube
- a cup made of plastic = a plastic cup
- a wall made of bricks = a brick wall
Nouns ending in ‘-er/-or’ and ‘ing’
- Someone who owns cars = a car owner
- Someone who manufactures cars = a car manufacturer
- Someone who directs films = a film director
- Something to peel potatoes = a potato peeler
- a list for shopping = a shopping list
- a pool for swimming = a swimming pool
- a machine for washing = a washing machine
- a stick for walking = a walking stick
- a holiday for walking = a walking holiday
Exceptions and alternatives
In the ‘nouns as adjectives’ list of errors above, we saw that you do NOT need any kind of ‘s’ (no possessive ‘s’ or plural ‘s’).
However, there are some exceptions.
Plural ‘s’ is used in these examples:
- a clothes shop
- the ladies room
- a sports car
- the arms race
- a singles bar
- a news editor
- an admissions policy,
- a maths lesson (U.S. – Math lesson)
- sales figures
- materials design
- customs officers
Possessive ‘s’ is used with these irregular plurals:
- children’s literature
- women’s rights
Possessive ‘s’ is also correct in these examples (both options are correct):
- a summer day = a summer‘s day
- The rays of the sun = the sun‘s rays
- The milk of cows = cows’ milk
- A day for Mothers = Mothers’ Day
- Shakespeare plays = Shakespeare‘s plays
- The influence of television = television‘s influence
- The government’s policy (‘government’ is a noun here, so we need possessive ‘s’ = of the government)
- Government policy (‘government’ is an adjective here, so no possessive ‘s’ is required)
- Water management (general)
- The management of water (specific)
Many nouns are also adjectives e.g.
human, chemical, adult, alternative, classic, individual, minimum, transport, professional, male, female, animal, wildlife.
Other mistakes that occur, often in Speaking, are:
- Advice about health = health advice (not
- A course about photography = a photography course (not
‘Hanging hyphens’ – don’t do this
If you just take away one thing from this lesson, it is that you should think twice about using an ‘s’ on words that describe nouns.
Keep it simple and drop the ‘s’.
