What is a Definite Article and an Indefinite Article

Definite Articles and Indefinite Articles

1. Articles are Adjectives

A, an, and the are articles and they belong to the adjective family. Articles act like adjectives because they point to nouns.

2. Articles Modify Nouns

The is referred to as the definite article because it limits the meaning to one specific person, place or thing and to no other.

A and an are referred to as indefinite articles because they do not limit the meaning to one specific person, place or thing.

Article Usage

The indefinite articles a and an have the same meaning. Which to use is determined by the pronunciation of the word that follows.

The initial sound of a word (not its spelling) determines whether to use a or an.

An is used before all vowel sounds except the sound of u (a unit, a university or a united front).

An precedes abbreviations that begin with a vowel sound, numbers that begin with a vowel sound and words that begin with a silent h sound (an honest man or an hour).

Articles That Precede Adjectives

When two or more adjectives describe the same noun, us the article before the first adjective.

When two or more adjectives describe different nouns, use the article before each adjective.

Articles That Precede Nouns

When nouns seem to form a single whole, place the article before the first noun only.

When the nouns refer to different persons or things, place the article before each noun.

Sometimes the indefinite article is used incorrectly before a noun especially when the word kind is used.
