There are two types of articles:the definite article (the) and the indefinite articles (a, an). We usually use the indefinite article first to mention some person or thing. By doing that, we don’t have to be clear about which particular person or thing we are referring to. When we refer to the same person or thing again, we use the definite article the to indicate the person or thing already mentioned.

There are times when we don’t have to use any one of the articles. Such non-use of the article is given the name zero article, so we are actually using the zero article when we are not using an article. Having a clear understanding of the different articles enables us to choose the right articles to use.
