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 abook," 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. So...
- a + singular noun beginning with a consonant: a boy; a car; a bike; a zoo; a dog
- an + singular noun beginning with a vowel: an elephant; an egg; an apple; an idiot;an orphan
- a + singular noun beginning with a consonant sound: a user (sounds like 'yoo-zer,' i.e. begins with a consonant 'y' sound, so 'a' is used); a university; a unicycle
- an + nouns starting with silent "h": an hour
- a + nouns starting with a pronounced "h": a horsen some cases where "h" is pronounced, such as "historical," you can use an. However, a is more commonly used and preferred.A historical event is worth recording.
Definite Article: the
The definite article is used before singular and plural nouns when the noun is specific or particular. The signals that the noun is definite, that it refers to a particular member of a group. For example:
"The dog that bit me ran away." Here, we're talking about a specific dog, the dog that bit me.
"I was happy to see the policeman who saved my cat!" Here, we're talking about aparticular policeman. Even if we don't know the policeman's name, it's still a particular policeman because it is the one who saved the cat.
"I saw the elephant at the zoo." Here, we're talking about a specific noun. Probably there is only one elephant at the zoo.
Countable and Uncountable Nouns
The can be used with uncountable nouns, or the article can be omitted entirely.
- "I love to sail over the water" (some specific body of water) or "I love to sail over water" (any water).
- "He spilled the milk all over the floor" (some specific milk, perhaps the milk you bought earlier that day) or "He spilled milk all over the floor" (any milk).
"A/an" can be used only with countable nouns.
- "I need a bottle of water."
- "I need a new glass of milk."
Most of the time, you can't say, "She wants a water," unless you're implying, say, a bottle of water.
Geographical use of the
