Articles: Basic Rules

An article is a functional word which we use with a noun to show its definiteness or indefiniteness. There are 2 types of articles in English: indefinite (a/an) and definite (the). The term zero article refers to occasions when there is no article preceding a noun (or a noun phrase). Here is basic information about how to use articles with different kinds of noun:
