Compound Nouns
A compound noun is a noun that is made with two or more words. A compound noun is usually [noun + noun] or [adjective + noun], but there are other combinations (see below). It isimportant to understand and recognize compound nouns. Each compound noun acts as a single unit and can be modified by adjectives and other nouns.
There are three forms for compound nouns:
1.open orspaced - space between words (tennis shoe)
2.hyphenated - hyphen between words (six-pack)
3.closed or solid - no space or hyphen between words (bedroom)

verb(-ing) + noun
breakfast

washing machine

Pronunciation
Compound nouns tend to have more stress on the first word. In the phrase "pink ball", both words are equallystressed (as you know, adjectives and nouns are always stressed). In the compound noun "golf ball", the first word is stressed more (even though both words are nouns, and nouns are always stressed).Since "golf ball" is a compound noun we consider it as a single noun and so it has a single main stress - on the first word. Stress is important in compound nouns. For example, it helps us know ifsomebody said "a GREEN HOUSE" (a house which is painted green) or "a GREENhouse" (a building made of glass for growing plants inside).

British/American differences
Different varieties of English, andeven different writers, may use the open, hyphenated or closed form for the same compound noun. It is partly a matter of style. There are no definite rules. For example we can find:
•container ship•container-ship
•containership

If you are not sure which form to use, please check in a good dictionary.
