Articles (English Grammar)

The articles are the words "a," "an," and "the." They define whether something is specific or unspecific. There are two types of article:

(1) The Definite Article (The). "The" is called the definite article. It defines its noun as something specific (e.g., something previously mentioned or known, something unique, something being identified by the speaker).

• This is the lake.
(This is a previously specified lake, i.e., one already known to the readers.)

(2) The Indefinite Article (A, An). "A" and "an" are called the indefinite articles. They define their noun as something unspecific (e.g., something generic, something mentioned for the first time).

• This is a lake.
(This is a previously unspecified lake.)

The Two Types of Article

"The" is called the definite article because it is used to indicate something specific. "A and an" are called the indefinite articles because they are used to indicate something unspecific.
