Definition of articles
English has two types of articles: definite (the) and indefinite (a, an.) The use of these articles depends mainly on whether you are referring to any member of a group, or to a specific member of a group:
1. Indefinite Articles: a and an
A and an signal that the noun modified is indefinite, referring to any member of a group. These indefinite articles are used with singular nouns when the noun is general; the corresponding indefinite quantity word some is used for plural general nouns. The rule is:
If the noun is modified by an adjective, the choice between a and an depends on the initial sound of the adjective that immedately follows the article:
Note also that in English, the indefinite articles are used to indicate membership in a profession, nation, or religion.
2. Definite Article: the
The definite article is used before singular and plural nouns when the noun is particular or specific. The signals that the noun is definite, that it refers to a particular member of a group or the noun we already know about. Compare the indefinite and definite articles in the following examples:
Indefinite (a or an)
a dog (any dog)
the dog (that specific dog)
some dogs (any dogs)
the dogs (those specific dogs)
The is not used with noncountable nouns referring to something in a general sense:
[no article] Coffee is a popular drink.
[no article] Japanese was his native language.
[no article] Intelligence is difficult to quantify.
The is used with noncountable nouns that are made more specific by a limiting modifying phrase or clause:
The coffee in my cup is too hot to drink.
The Japanese he speaks is often heard in the countryside.
The intelligence of animals is variable but undeniable.
The is also used when a noun refers to something unique:
the White House
the theory of relativity
the 1999 federal budget
Note: Geographical uses of the
Do not use the before:
Do use the before:
When do we say "the dog" and when do we say "a dog"? (On this page we talk only about singular, countable nouns.)
The and a/an are called "articles". We divide them into "definite" and "indefinite" like this:
We use "definite" to mean sure, certain. "Definite" is particular.
We use "indefinite" to mean not sure, not certain. "Indefinite" is general.
When we are talking about one thing in particular, we use the. When we are talking about one thing in general, we use a or an.
Think of the sky at night. In the sky we see 1 moon and millions of stars. So normally we would say:
Look at these examples:
Of course, often we can use the or a/an for the same word. It depends on the situation, not the word. Look at these examples:
This little story should help you understand the difference between the and a, an:
A man and a woman were walking in Oxford Street. The woman saw a dress that she liked in a shop. She asked the man if he could buy the dress for her. He said: "Do you think the shop will accept a cheque? I don't have a credit card."
Further Uses of Articles
In addition, use of a, an, and the also depends on whether the noun following the article possesses one of these paired qualities:
1. Countable vs. Noncountable
A and an are used if the noun can be counted.
I stepped in a puddle. (How many puddles did you step in? Just one. Therefore, use a.)
I drank a glass of milk. (Glasses of milk can be counted)
I saw an apple tree. (Apple trees can be counted)
The must be used when the noun cannot be counted.
I dove into the water. (How many waters did you dive into? The question doesn't make any sense because water is noncountable. Therefore, use the.)
I saw the milk spill. (How many milks? Milk cannot be counted)
I admired the foliage. (How many foliages? Foliage cannot be counted)
2. First vs. Subsequent Mention
A or an is used to introduce a noun when it is mentioned for the first time in a piece of writing. The is used afterward each time you mention that same noun.
An awards ceremony at the Kremlin would not normally have attracted so much attention. But when it was leaked that Soviet President Konstantin Chernenko would be presenting medals to three cosmonauts, interest in the ceremony intensified. Time, Sept. 17, 1984.
Note: There is and there are can be used to introduce an indefinite noun at the beginning of a paragraph or essay.
There is a robin in the tree outside my window. When my cat jumps up on the desk, the robin flies away.
3. General vs. Specific
A, an, and the can all be used to indicate that a noun refers to the whole class to which individual countable nouns belong. This use of articles is called generic, from the Latin word meaning "class."
A tiger is a dangerous animal. (any individual tiger)
The tiger is a dangerous animal. (all tigers: tiger as a generic category)
The difference between the indefinite a and an and the generic a and an is that the former means any one member of a class while the latter means all of the members of a class.
The omission of articles also expresses a generic (or general) meaning:
no article with a plural noun: Tigers are dangerous animals. (all tigers)
no article with a noncountable noun: Anger is a destructive emotion. (any kind of anger)
Omission of Articles
While some nouns combine with one article or the other based on whether they are countable or noncountable, others simply never take either article. Some common types of nouns that don't take an article are:
1. Names of languages and nationalities
2. Names of sports
3. Names of academic subjects
A or An?
"A" goes before all words that begin with consonants.
with one exception: Use an before unsounded h.
"An" goes before all words that begin with vowels:
with two exceptions: When u makes the same sound as the y in you, or o makes the same sound as w in won, then a is used.
Note: The choice of article is actually based upon the phonetic (sound) quality of the first letter in a word, not on the orthographic (written) representation of the letter. If the first letter makes a vowel-type sound, you use "an"; if the first letter would makes a consonant-type sound, you use "a." So, if you consider the rule from a phonetic perspective, there aren't any exceptions. Since the 'h' hasn't any phonetic representation, no audible sound, in the first exception, the sound that follows the article is a vowel; consequently, 'an' is used. In the second exception, the word-initial 'y' sound (unicorn) is actually a glide [j] phonetically, which has consonantal properties; consequently, it is treated as a consonant, requiring 'a'.
