Should I use an indefinite article (a/an) or a definite article (the)?

ARTICLES

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

English has two articles: the and a/an.
·       the = definite article used to refer to specific or particular nouns
·       a/an = indefinite article used to modify non-specific or non-particular nouns; "A/an" is used to refer to a non-specific or non-particular member of the group
o   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 (a non-particular book) rather than a specific book.

Omission of Articles

Not all nouns need articles. Some common types of nouns that don't take an article are:
  • Names of languages and nationalities: Chinese, English, Spanish, Russian (unless you are referring to the population of the nation in general: "The Spanish are known for their warm hospitality.")
  • Names of academic subjects: mathematics, biology, history, computer science

Exercise
· Find and circle all of the articles in your paper.
· Can you tell which nouns require definite and indefinite articles, and which require no article at all?
Homework – Find and fix any mistakes in your use of articles.

In addition to MS Word spell check, you might try Vince's "Google that stuff" (GTS) method.
1.     Put your article phrase in quotation marks and search Google (.com English version, not co.jp).
·       Example: "the veracity of a theory" (I could not find any instances of "a veracity of a theory." Therefore, this phrase always uses the definitive article ("the")
2.     If professionally edited sites (not personal blogs) use the phrase as you have written it, then your articles are probably correct.
3.     On the other hand, if you only find a few examples, or none at all, then you should probably use a different article, or none at all.

Try Vince's GTS method with the following phrases:
Can you find any indefinite article phrases for the following? (I could not.)
·       "The Data Encryption Standard"
·       "the Earth's crust"
·       "the opposite polarity"
·       "the power of reasoning"
·       "the Secure Sockets Layer"
·       "the theory of relativity"

I found instances of both definite and indefinite articles for the following phrases:
·       "a carbon footprint" and "the carbon footprint" (e.g. of The carbon footprint an iPhone)
·       "a symbiotic relationship” and. "the symbiotic relationship" (e.g. The symbiotic relationship between humans and domesticated animals)
·       "an outlier from the data" and "the outlier from the data" (e.g. How does removing the outlier from the data affect the mean and the median?)

Vince's final observation: I believe the process of learning English articles is somewhat similar to the process of learning Japanese counter words (josūshi 助数詞), which are used along with numbers to count things, actions, and events. Someone learning Japanese simply needs to memorize the proper use of these unique grammatical structures. Perhaps English articles are similar in this regard. Therefore, if you read (and write) English every day, you will eventually develop instincts to differentiate definite and indefinite articles.


Even writers who grew up in English-speaking countries struggle with articles. 

Here are some tips from the Purdue Online Writing Lab (OWL), which is a fantastic resource.

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. 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 horse
    • In 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.

Remember that these rules also apply when you use acronyms:


  • Introductory Composition at Purdue (ICaP) handles first-year writing at the University. Therefore, an ICaP memo generally discusses issues concerning English 106 instructors.

Another case where this rule applies is when acronyms start with consonant letters but have vowel sounds:


  • An MSDS (material safety data sheet) was used to record the data. An SPCC plan (Spill Prevention Control and Countermeasures plan) will help us prepare for the worst.

If the noun is modified by an adjective, the choice between a and an depends on the initial sound of the adjective that immediately follows the article:
  • a broken egg
  • an unusual problem
  • a European country (sounds like 'yer-o-pi-an,' i.e. begins with consonant 'y' sound)
Remember, too, that in English, the indefinite articles are used to indicate membership in a group:
  • I am a teacher. (I am a member of a large group known as teachers.)
  • Brian is an Irishman. (Brian is a member of the people known as Irish.)
  • Seiko is a practicing Buddhist. (Seiko is a member of the group of people known as Buddhists.)
 

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 a particular 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.

Count and Noncount Nouns

The can be used with noncount 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 count 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

There are some specific rules for using the with geographical nouns.
Do not use the before:
  • names of most countries/territories: Italy, Mexico, Bolivia; however, thethe Dominican Republic, the Philippines, the United States Netherlands,
  • names of cities, towns, or states: Seoul, Manitoba, Miami
  • names of streets: Washington Blvd., Main St.
  • names of lakes and bays: Lake Titicaca, Lake Erie except with a group of lakes like the Great Lakes
  • names of mountains: Mount Everest, Mount Fuji except with ranges of mountains like the Andes or the Rockies or unusual names like the Matterhorn
  • names of continents (Asia, Europe)
  • names of islands (Easter Island, Maui, Key West) except with island chains like the Aleutians, the Hebrides, or the Canary Islands

Do use the before:
  • names of rivers, oceans and seas: the Nile, the Pacific
  • points on the globe: the Equator, the North Pole
  • geographical areas: the Middle East, the West
  • deserts, forests, gulfs, and peninsulas: the Sahara, the Persian Gulf, the Black Forest, the Iberian Peninsula 

Omission of Articles

Some common types of nouns that don't take an article are:
  • Names of languages and nationalities: Chinese, English, Spanish, Russian (unless you are referring to the population of the nation: "The Spanish are known for their warm hospitality.")
  • Names of sports: volleyball, hockey, baseball
  • Names of academic subjects: mathematics, biology, history, computer science
