Adjectives are words that describe nouns. In the sentence,
Bob is reading a funny book;
the adjective funny tells us what kind of book Bob is reading.
Adjectives help us tell more about nouns.
We say that adjectives modify nouns. Modify means to change a little.
An adjective changes a noun by telling more about the noun.
Adjectives can come immediately before the noun they modify.
For example, in the following sentence,
John wore a red shirt.
The adjective red comes before the noun shirt.
Adjectives can also come after the ~to be~ verb as in the following sentence.
John is intelligent.
Adjectives do not have plural forms so they never end in an ~s.
Roses are beautiful flowers.
NOT Roses are beautifuls flowers. Using nouns as adjectives.
Sometimes nouns can be used as adjectives.
For example, flower is normally a noun, but in the sentence,
Mary has a flower garden.
flower is functioning as an adjective to describe Mary's garden.
What kind of garden does Mary have? Mary has a flower garden.
When a noun is used as an adjective, the noun is singular NOT plural.
