Are the demonstrative pronouns and plural or singular?

Demonstrative pronouns can be singular or plural, depending on what they're referring to. Here's a breakdown:

Singular Demonstrative Pronouns:

* This: Refers to a single, nearby object or person.

* Example: "This book is my favorite."

* That: Refers to a single, distant object or person.

* Example: "That dog is barking at the mailman."

Plural Demonstrative Pronouns:

* These: Refers to multiple, nearby objects or people.

* Example: "These flowers are beautiful."

Key Takeaway: The demonstrative pronoun's singularity or plurality is determined by what it's referring to, not the pronoun itself.
