Explain the usage of determiners with demonstrative pronouns.

Determiners are words that are used to modify nouns and provide more information about them. They help to specify or determine the noun they are referring to. Demonstrative pronouns, on the other hand, are a type of pronoun that are used to point to or identify a specific noun in a sentence. They include words like "this," "that," "these," and "those."

When determiners are used with demonstrative pronouns, they further clarify or specify the noun being referred to. They indicate the proximity of the noun in relation to the speaker and the listener. Let's take a closer look at the usage of determiners with demonstrative pronouns:

1. This: "This" is used to refer to a singular noun that is close to the speaker. It indicates something that is nearby in space or time. For example:
- This book is mine. (referring to a book that is close to the speaker)
- This is my car. (referring to a car that is close to the speaker)

2. That: "That" is used to refer to a singular noun that is far from the speaker. It indicates something that is distant in space or time. For example:
- That house is beautiful. (referring to a house that is far from the speaker)
- That is my friend. (referring to a person who is far from the speaker)

3. These: "These" is used to refer to plural nouns that are close to the speaker. It indicates multiple things that are nearby in space or time. For example:
- These books are mine. (referring to books that are close to the speaker)
- These are my keys. (referring to keys that are close to the speaker)

4. Those: "Those" is used to refer to plural nouns that are far from the speaker. It indicates multiple things that are distant in space or time. For example:
- Those houses are expensive. (referring to houses that are far from the speaker)
- Those are my friends. (referring to people who are far from the speaker)

In summary, determiners are used with demonstrative pronouns to provide more specific information about the noun being referred to. They indicate the proximity of the noun in relation to the speaker and the listener, whether it is close or far in space or time.
