What is a definite adjective?

The term "definite adjective" is not a standard grammatical term. There's no recognized category of adjectives called "definite."

Here's what might be causing confusion:

* "Definite" as a general word: The word "definite" is often used to describe something that is specific, certain, or clear. For example, "I have a *definite* plan for the weekend."

* "Definite articles" in grammar: The definite article "the" is used to specify a particular noun. It indicates that the noun is known or understood by both the speaker and the listener.

To clarify, adjectives describe nouns, while articles like "the" help define the noun's specificity.
