An article (abbreviated to ART) is a word (prefix or suffix) that is used alongside a noun to indicate the type of reference being made by the noun. Articles specify grammatical definiteness of the noun, in some languages extending to volume or numerical scope.
Plot of the subject of the article: If the subject of the article is a book or film or other artistic work, it is unnecessary to cite a source in describing events or other details. It should be obvious to potential readers that the subject of the article is the source of the information.
