Adjectives: form and position π

An adjective describes a noun: big, red, happy, expensive.
Adjectives never change
In English, the adjective has the same form with all nouns. It does not change for singular, plural, or masculine and feminine words.
| Singular | Plural |
| a big house | two big houses |
| a happy man | happy women |
β two bigs houses
β two big houses
Two positions
Before the noun:
a new car
cold water
After the verbs be, look, feel, seem, become, get, taste, smell, sound:
The car is new.
You look tired.
This soup tastes good.
Adjectives cannot stand alone as a noun
Use one or ones instead of repeating the noun:
I don't like the red shirt. I like the blue one.
These shoes are old. I need new ones.
β I like the blue.
β I like the blue one.
