what is definite article

A definite article is a type of article that is used before a noun to indicate that the identity of the noun is known to the reader. In English, the definite article is "the." It is used when the speaker believes that the listener already knows what they are referring to, or when the noun refers to a specific person or thing. For example, "the car," "the sun," "the president." The definite article is also used when assuming there is only one of something in a place, or when defining or identifying a particular person or object
