*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).
*Adjective of quantity
An adjective of quantity tells us the number (how many) or amount (how much) of a noun.
A demonstrative adjective (this, that, these, those) shows the noun it modifies is singular or plural and whether the position of the noun is near or far from the person who is speaking or writing. A demonstrative adjective also points out a fact about the noun.
A possessive adjective expresses possession of a noun by someone or something. Possessive adjectives are the same as possessive pronouns.
