The problem of the number of articles (how many morphological forms the Article can be presented in)

There are two approaches (traditional Grammar and contemporary approach):

1) there are two articles in English (drawing 4.1): definite and indefinite (the Category of Article is based on the opposition);

2) there are three articles (table 4.1): zero, definite and indefinite (the Category of Article is grounded on the proper correlation of the absence, emphasis on the definite character of the Noun and emphasis on the indefinite character of the Noun). The absence of Article is regarded to be a relevant characteristics as it has the meaning (identifying a thing as a general phenomenon) and two properly correlated characteristics – identifying a definite and indefinite things.
