Noun Adjuncts (noun + noun)
In English we can put two nouns together. The first noun is used as an adjective to modify the second noun and is called a noun adjunct. The first noun is almost always singular because it follows the rule for adjectives, which do not have plural forms in English.
N1 N2 can mean that
a. N1 is a kind of N2 (a grammar book is a kind of book)
b. N1 is an object of an implied verb (an apple tree is a tree that produces apples)
It is important to understand that N2 is the thing and N1 is the kind or type:
a rose bush is a busha wrist watch is a watchcomputer paper is paper
N1 is singular, even if the phrase is plural.
My mother planted a rose bush in the garden.
I bought a new table lamp.
Bobby takes the school bus to school.
The school ordered fifty new grammar books.
That man makes bird cages.
Mrs. Taylor bought some new baby clothes.We can use a number with N1 to make a compound adjective. Since the number and noun make one unit, we use a hyphen to join them. Note that N1 remains singular because it is being used as an adjective.
a three-car garage
a ten-speed bicycle
a twenty-dollar bill
If we use a number to refer to the second noun (how many), we do not use a hyphen:
two grammar books
five rose bushes
We can use a number to refer to the second noun (how many) and a number with the first noun (compound adjective). In that case, there is no hyphen after the first number, but the second number is still used with a hyphen because it forms a compound adjective.
Determiners are words that are used with nouns to clarify the noun. They can clarify:
***to define something or someone***to state the amount of people, things or other nouns ***to state possessives***to state something or someone is specific***to state how things or people are distributed***to state the difference between nouns***to state someone or something is not specific
There are different types of determiners. There type of determiner depends on the type of noun. Singular nouns always need a determiner. Plural nouns the determiner is optional. Uncountable nouns the determiner is also optional.
There are about 50 different determiners in the English language they include:
1. Articles: a, an, the
2.Demonstratives: this, that, these, those, which etc.
3.Possessives: my, your, our, their, his, hers, whose, my friend's, our friends', etc.
