* Definite articles point to a specific noun.
* Indefinite articles (like "a" and "an") point to any noun of that type.
Here's a breakdown:
* "The" is always definite. It refers to something specific, already known, or unique.
* Example: "The book on the table" (specific book)
* "A" and "an" are indefinite. They refer to any one of a group of nouns.
* Example: "A book" (any book)
