English articles

The articles in English are the definite article the and the indefinite articles a and an. They are the two most common determiners. The definite article is the default determiner when the speaker believes that the listener knows the identity of a common noun's referent (because it is obvious, because it is common knowledge, or because it was mentioned in the same sentence or an earlier sentence). The indefinite article is the default determiner for other singular, countable, common nouns, while no determiner is the default for other common nouns. Other determiners are used to add semantic information such as amount (many, a few), proximity (this, those), or possession (my, the government's).
