What Are Articles?

Articles are special adjectives that come before nouns. English has only three articles: a, an, and the. They help specify whether we're talking about something general or specific.

The Two Types of Articles

Indefinite Articles

A and An

Used for non-specific, singular countable nouns

Examples:

  • "a dog" (any dog)
  • "an apple" (any apple)

Definite Article

The

Used for specific nouns (singular or plural)

Examples:

  • "the dog" (a specific dog)
  • "the apples" (specific apples)
The Golden Rule
Use "a" or "an" when talking about something for the first time or any one of a group
Use "the" when talking about something specific that both speaker and listener know about

Indefinite Articles: A & An

Used with non-specific singular countable nouns

"A" vs "An" Beginner

The choice between "a" and "an" depends on the sound (not the letter) that follows. This is about pronunciation, not spelling!

The Sound Rule
Use "a" before words that start with a consonant SOUND
Use "an" before words that start with a vowel SOUND

Remember: It's about the SOUND, not the letter!
