Using one noun to modify another noun.
English frequently uses one noun to modify another noun.
The first noun functions like an adjective by describing the type, purpose or category of the second noun.
The first noun usually describes purpose, material, location, content, source or type rather than possession.
Examples include coffee cup, school bus, stone wall and office chair.
The modifying noun is usually singular, even when the meaning is plural.
Examples include shoe shop, apple tree, toothbrush and computer program.
Some modifier nouns remain plural because they exist mainly or only in the plural form.
Examples include sports car, arms race, clothes shop and customs officer.
Nouns expressing measurement often modify another noun.
Examples include a five-kilometer race, a ten-dollar bill and a two-hour meeting.
English allows several nouns to appear before the head noun.
Examples include computer software development company and city transport planning committee. Long noun strings should be used carefully to maintain clarity.
A noun modifier describes a type or category, while a possessive noun expresses ownership or relationship.
Compare children's hospital (hospital for children) with the children's hospital (hospital belonging to the children).
Nouns and adjectives may both modify nouns, but they have different grammatical functions.
Compare stone wall with strong wall and history teacher with historical teacher.
Noun + noun combinations usually receive primary stress on the first noun.
Compare GREENhouse (building) with green HOUSE (a house that is green).
Some noun combinations become fixed vocabulary items with meanings that are not entirely predictable.
Examples include blackboard, football and breakfast.
Keep the modifier noun singular in most noun+noun combinations and distinguish classification from possession.
Common mistakes include using unnecessary plural modifiers, confusing possessives with noun modifiers and placing stress on the wrong word.
