What are the examples of articles as a part od speech?

You're asking about the examples of articles, but "article" is a word class (part of speech), not something that has examples. The examples would be the *words* that are classified as articles.

Here's the breakdown:

* Articles are a type of determiner, words that specify which noun is being referred to.

* English has two types of articles:

* Definite article: "the" (refers to a specific noun already known)

* Indefinite articles: "a" and "an" (refers to any noun from a general group)

Here are some examples of articles in sentences:

* "The" cat sat on the mat. (Both "the" are definite articles)

* "A" dog chased a ball. (Both "a" are indefinite articles)

* "An" apple a day keeps the doctor away. ("An" is an indefinite article)

To summarize: Articles are words, not things that have examples. The examples are the actual words that fall into the category of articles.
