Main Difference – Demonstrative Adjective vs Demonstrative Pronoun
The four terms this, these, that and those are used to identify and indicate specific objects or people. These four terms can be used either as demonstrative adjectives or demonstrative pronouns. Although these terms are used for both demonstrative adjectives and demonstrative pronouns, there is a big difference between them based on their function and use. The main difference between demonstrative adjectives and demonstrative pronouns is that demonstrative adjectives modify a noun whereas demonstrative pronouns replace a noun.
What is a Demonstrative Pronoun
A pronoun is a word that can replace a noun. A demonstrative pronoun is a pronoun that is used to replace a specific person or thing that has been previously mentioned or is understood from the context. It is used to indicate something specific within a sentence. The four demonstrative pronouns in English include this, that, these and those. They can refer to things in space or time, and they can be either singular or plural.
This and these refer to items that are close by in space or time whereas that and those refer to things that are far away in space or time. This and that refer to singular nouns whereas these and those refer to plural nouns.
Nearby in Space and Time
Farther away in Space and Time
This is my mother.
Can you pass me one of those?
That is my house over there.
These are not yours.
I don’t like this.
As you can observe from the above examples, demonstrative pronouns can stand alone; they are not followed by a noun or a noun phrase.
