Articles are words that combine with a noun to indicate the degree of definiteness (specificity) of the reference being made by the noun. The articles in English are the definite article the and the indefinite articles a and an (and sometimes some). Use of the definite article implies that the speaker assumes the listener knows the identity of the 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). Use of an indefinite article implies that the speaker assumes the listener does not know the identity of the referent.

In English, nouns must in most cases be preceded by an article that specifies the presence or absence of definiteness of the noun. The definite article is the in all cases other than generic references, which use the zero article (i.e., the absence of an article), while indefiniteness is expressed with a or an for singular nouns or the zero article for plural or non-count nouns.

After a self-imposed European exile in the early 1980s, Gaye returned on the 1982 Grammy-Award winning hit, "Sexual Healing" and the Midnight Love album before his death.
