Articles (the, a, and an) help say what kind of noun you are talking about. To make it easier, there are a few rules for you to follow.


Basic Vocabulary

Before getting to the usage, it’s helpful to know the vocabulary below.

  • Vowels: letters A, E, I, O, U.
  • Consonants: any letter that isn’t a vowel. These are letters like B, C, D, F, etc.
  • Proper nouns: names of people, places or things such as David, Germany, or Samsung.
  • Singular count nouns: can be counted, but are only one unit, as in key, prison, and getaway.
  • Plural count nouns: countable nouns that have more than one unit (officers, dogs, and search parties).
  • Non-countable nouns: cannot be counted. This is true for things like cheese, milk, and patience.



Use a or an with singular count nouns. A comes before words that start with consonants; an comes before words the begin with vowels: A little dog can make an awful lot of noise.

Use the when the noun is:

1. unique (there’s only one)

  • The moon shone over the Pacific Ocean.

2. specific (the listener is familiar with it)

  • Go to the supermarket on your way home from the bank.

3. mentioned a second time

4. superlative

*When a country is officially divided, it is possible to refer to the parts together with the plus –s.

Avoid using articles for:
