In English, there are three articles: "a/an" which are called indefinite article and "the" which is called definite article. Articles are used before nouns or noun equivalents and are a type of adjective. The definite article is used before a noun to indicate that the identity of the noun is known to the reader. The indefinite article is used before a noun that is general or when its identity is not known. The definite article "the" is the most frequent word in English.
