Demonstrative Adjectives

                Demonstrative adjectives are used when there is a need to point specific things. The adjectives function as a way to demonstrate something and are similar to demonstrative pronouns. Here words such as this, that, these, those and what are used. Take, for instance, the sentence: 'If I hear that sound again, I will call the Police'. Here 'that' refers to a specific sound. Other examples are as follows:

    Whose is this bag?

    These mangoes are sour.
