An article is a word used to modify a noun, which is a person, place, object, or idea.

There are two articles in English: the definite article and the indefinite article.


The indefinite article has two forms: a and an. The form a is used befire words beginning with a consonant: a pen, a doctor, a ruler, a table. The form an is used before words beginning with a vowel: an idea, an elephant, an owl, an apple. 

The indefinite article originated from the Old English numeral an (one). As a result of its origin it is used only with countable nouns in the singular.

We use the indefinite article a / an:

  • with singular countable nouns when we mention something for the first time, talk about something unknown or without any details: I watched a car as it came up our road. The car stopped and a man got out. The man was carrying a case.
  • when we talk about people or things “in general”: A cat is a domestic animal. (= cats in general). A baker bakes bread. (Bakers in general)
