A demonstrative pronoun is a type of pronoun that points to a specific noun or pronoun in a sentence. These pronouns are used to indicate distance, whether the object is near or far from the speaker or the listener. Some common synonyms for demonstrative pronouns include indicative pronouns, pointing pronouns, and indicating pronouns. These pronouns can be further classified into two categories: proximal and distal. Proximal pronouns are used to refer to objects that are close to the speaker or listener, while distal pronouns are used for objects that are far away. Common examples of demonstrative pronouns include this, that, these, and those.
