difference between articles and adjectives

An article is a word used to modify a noun, which is a person, place, object, or idea. Technically, an article is anadjective, which is any word that modifies a noun. Usually adjectives modify nouns through description, but articles are used instead to point out or refer to nouns. There are two different types of articles that we use in writing and conversation to point out or refer to a noun or group of nouns: definite and indefinite articles.
