The main purpose of this thesis is intended to provide some linguistic appropriateness or adequacy of the classification of the English article. In this thesis, several different classifications of the English article have been treated under the following topics: (1) four types classified by Huebner(1985), (2) the fifth type explained by Yoko Goto(1999) and (3) the sixth type suggested by the present writers. Section 1∼4 have discussed the classification derived from the different semantic functions which the English articles (Indefinite, Definite and Zero articles) have. We have analyzed so many example sentences in order to clarify semantic distinctions or differences occurring among the types established by Huebner. Section 5 has treated the idiomatic usage of the article including proper nouns with heterogeneous characteristics in English. Section 6 has suggested the new classification asserted by the writers of the English article. We have mentioned that such classification to clarify semantic distinctions and differences heavily depends on the content or the nature of the article. It may be given as a conclusion that all the classifications and some different uses of the English article have been discussed, analyzed, and determined according to the semantic functions.
