The different kinds of adjectives are discussed in detail in under their respective sections:

Descriptive adjective or adjective of quality

Descriptive adjectives are the most numerous of the different types of adjectives. These adjectives describe nouns that refer to action, state, or quality (careless, dangerous, excited, sad, black, white, big, small, long, fat, English, Mediterranean, three-cornered).

 plural

Examples:

  • dangerous chemicls
  • green vegetables
  • a square box
  • a big house
  • a tall tree
  • a cold morning
  • a true story
  • English language
  • Mediterranean couintry

 

Adjective of quantity

An adjective of quantity tells us the number (how many) or amount (how much) of a noun.

 plural

Examples:

  • He has eaten three apples.
  • I don't have much money.
  • There is so much wine for the guests.
  • This long, thin centipede has many legs.

 

Demonstrative adjective

There are four words that are used as demonstrative adjectives: this, that, these, those. We use this and that with nouns to show the nouns are singular (this/that box = one box) and these and those with nouns to show they are plural (these/those apples = more than one apple). 

 plural

Examples:

  • This dog had no tail.
  • That cat is fat.
  • These giraffes have long necks.
  • Those monkeys are noisy.

 

Demonstrative adjectives coming before nouns tell us whether the position of the noun is near or far from the person who is speaking or writing. This should show clearly which thing or things the speaker refers to: 

 plural

Examples:

  • This balloon is mine and those are yours.
  • This cute baby is his brother. That cute baby is his sister.
  • These two apples have worms, and that one is rotten.

 

In the first example, the listeners should understand which balloon or balloons the speaker refers to in the sentence.

 
The four words that make up the demonstrative adjectives are also called demonstrative determiners. Demonstrative determiners like demonstrative adjectives are used before a noun to show which particular example of the noun is being referred to. 
 
Demonstrative adjectives should not be confused with demonstrative pronouns. Whether they are demonstrative adjectives or demonstrative pronouns depends on how they are used in a sentence. Demonstrative pronouns are not used used before a noun. Instead, they are used by themselves in place of a noun.
 

Possessive adjective

A possessive adjective expresses possession of a noun by someone or something. Possessive adjectives are the same as possessive pronouns. All the possessive adjectives are listed in the following table:
