Rules for Using Definite, Indefinite and Zero Articles

What are articles?

Articles are words that come before nouns to specify or limit their application. In English, there are three types of articles: definite, indefinite and zero.

• Definite Article (the): "the" is used to refer to specific nouns that are known to the speaker and the listener.

• Indefinite Articles (a/an): "a" is used before nouns that begin with a consonant sound, while "an" is used before nouns that begin with a vowel sound.

• Zero Article: the zero article is used when no article is required before a noun.
