the type of reference being made by the noun, and to specify the volume or numerical scope of that reference.

The articles in the English language are the and a (with variant form an). An article is sometimes called a noun marker, although this is generally considered to be an archaic term.[1]

Articles are traditionally considered to form a separate part of speech. They can be also thought of as a special kind of adjective, because they combine with a noun and contribute to the meaning of the noun phrase. Linguists place them in the category of determiners.
