The order is: Adjective + noun

We can also use the verb To Be + Adjective. For example…

After IS we put the adjective… IS GREEN.

Adjectives in English have one form.

For example the adjective red.

  • One red car.

Red is an adjective. It gives us more information about the car. We describe the car. The car is red.
When there is more than one car, for example two cars, the adjective RED does not change.
We say:

  • Two red cars.

Red is used with one car and Red is used for two cars.
We do not say two reds cars. No. (There is no S at the end of red)
