While articles are sometimes grouped under the broader category of "determiners", they are a distinct part of speech with their own unique function.
Here's why:
* Definite Articles: Indicate that the noun following it is a specific, already known item (e.g., "the book" refers to a particular book already understood).
* Indefinite Articles: Indicate that the noun following it is a general or unspecified item (e.g., "a book" refers to any book).
