    Using Articles

    Summary: This handout discusses the differences between indefinite articles (a/an) and definite articles (the).

    Contributors:Paul Lynch, Allen Brizee, Elizabeth Angeli

    What is an article? Basically, an article is an adjective. Like adjectives, articles modify nouns.

    English has two articles: the and a/an. The is used to refer to specific or particular nouns; a/an is used to modify non-specific or non-particular nouns. We call the the definite article and a/an the indefinite article.

    the = definite article

    a/an = indefinite article

    For example, if I say, "Let's read the book," I mean a specific book. If I say, "Let's read a book," I mean any book rather than a specific book.

    Here's another way to explain it: The is used to refer to a specific or particular member of a group. For example, "I just saw the most popular movie of the year." There are many movies, but only one particular movie is the most popular. Therefore, we use the.

    "A/an" is used to refer to a non-specific or non-particular member of the group. For example, "I would like to go see a movie." Here, we're not talking about a specific movie. We're talking about any movie. There are many movies, and I want to see any movie. I don't have a specific one in mind.

    Let's look at each kind of article a little more closely.

    Indefinite Articles: a and an

    "A" and "an" signal that the noun modified is indefinite, referring to any member of a group. For example:

    "My daughter really wants a dog for Christmas." This refers to any dog. We don't know which dog because we haven't found the dog yet.

    "Somebody call a policeman!" This refers to any policeman. We don't need a specific policeman; we need any policeman who is available.

    "When I was at the zoo, I saw an elephant!" Here, we're talking about a single, non-specific thing, in this case an elephant. There are probably several elephants at the zoo, but there's only one we're talking about here.

    Remember, using a or an depends on the sound that begins the next word.
