Adjectives are words used to tell us more about people or things. They usually describe nouns and are put before the nouns without changing their own forms.
This is a nice house.
It’s a rainy day.
There are many ripe red apples on the tree.
Sometimes adjectives are put after the verbs like ‘be’, ‘become’, ‘get’:
The sky is blue.
In autumn tree leaves become yellow and red.
It’s getting late, we need to go.
Adjectives can belong to different categories, each containing a number of types.
Fact adjectives provide factual information about the object they describe, e.g. its color, size, material, etc.
I saw a big car passing by the street (size type of adjective).
Young boys and girls go to school (age type of adjective).
Mary likes to wear white dresses in summer (color type of adjective).
The box is square, and the ball is round (shape type of adjective).
Tom brought a small porcelain cup from his trip to China (material type of adjective).
Do you like Vietnamese food? (origin type of adjective).
When we need to describe our thoughts about somebody or something, we can use opinion adjectives, such as ‘nice’, ‘beautiful’, ‘friendly’, etc.
Some of them are used to express general opinion (general opinion adjectives):
I have a beautiful cat (beautiful can describe various things)
My lovely dog plays all day round.
Others may be used to express more specific opinion (specific opinion adjectives):
The meal is delicious (delicious is normally used to talk about food).
Emily is a kind person (kind is normally used to talk about people).
