Adjectives - Demonstrative Adjectives

These adjectives answer the question ‘which?’

That house is mine (Ask the question ‘which house?’ and you get the answer ‘that’.) Keerti gave me this pen. (Ask the question ‘which pen?’ and you get the answer ‘this’.) I can solve these puzzles. (Ask the question ‘which puzzles?’ and you get the answer ‘these’.) Those boys were playing in the park. (Ask the question ‘which boys?’ and you get the answer ‘those’.) I don’t know why such questions are asked. (Ask the question ‘which questions?’ and you get the answer ‘such’.)

When a noun does not immediately follow ‘this’, ‘that’, ‘these’ and ‘those’, they are referred to as demonstrative pronouns.

This is my car. (‘This’ points to the object ‘my car’.) That is a banana. (‘That’ points to the object ‘a banana’.) These are good apples. (‘These’ points to the object ‘apples’.) Those are her shoes. (‘Those’ points to the object ‘her shoes’.)

[Remember: A noun does not immediately follow a demonstrative pronoun, while a demonstrative adjective always comes before a noun.]
