Are the words this that these and those articles?

You are close! But "this", "that", "these", and "those" are not technically articles. They are demonstrative pronouns.

Here's the breakdown:

* Articles are words that come before a noun to specify whether it's singular or plural, and whether it's definite (specific) or indefinite (general):

* Definite article: "the"

* Indefinite articles: "a" and "an"

* Demonstrative pronouns point to specific nouns or groups of nouns, showing their location in space or time:

* Singular: "this" (near), "that" (far)

* Plural: "these" (near), "those" (far)

Example:

* "The cat is on the mat." ("The" is the definite article)

* "This cat is on that mat." ("This" and "that" are demonstrative pronouns)
