 Demonstrative adjectives are used to show the location of the noun with reference to the speaker or writer. It also indicates the number of the noun referred to i.e. whether the noun is in the singular number or plural.

The words this, these, that, those, and what are demonstrative adjectives. We use them to tell our listeners which thing or person we mean.

Example:

This apartment needs to be painted.. (this is a demonstrative adjective to indicate which apartment)
He lives in this house

How much is that bag?
Bring me that book.

Would yo like these oranges?
I am keeping these pencils.

I am selling those books.
Please give me those clothes.

 Demonstrative adjectives show a) whether the noun they refer to is singular or plural and b) whether it is located near to or far from the speaker or narrator. The noun which is being pointed out always follows the demonstrative adjective. 
Example: Don't eat THOSE berries. I really love THAT man. THESE shoes are great.
Example #2:
Capitalize each demonstrative adjective. Put a star beside the noun that it specifies.
1. THIS *fruit is freshly picked from my orchard.
2. Do you know if THESE *sneakers are Mandy's?
The noun always comes after the demonstrative adjective.
