Articles: A, An, The — Definite and Indefinite Articles — Grammar Rules, Examples and Exercises — English 3rd Year Middle School — Algerian Curriculum

Articles: A, An, The

Articles are small but important words in English. They come before nouns and give information about them. There are two types: indefinite articles (A / An) and the definite article (The).

1. Indefinite Article: A / An

We use A and An before singular countable nouns when we talk about something for the first time or when it is not specific.

Article	Usage	Examples
A	Before words starting with a consonant sound	a book, a car, a university, a house
An	Before words starting with a vowel sound (a, e, i, o, u)	an apple, an egg, an hour, an umbrella

Important Notes

• We use a before words that begin with a consonant SOUND, even if the first letter is a vowel: a university, a European country, a one-way street.
• We use an before words that begin with a vowel SOUND, even if the first letter is a consonant: an hour, an honest man.
• We do NOT use a/an with plural or uncountable nouns: water | a water (wrong), books | a books (wrong)

2. Definite Article: The

We use The when we talk about something specific, unique, or already mentioned.

Usage	Examples
When something is already mentioned	I saw a cat. The cat was black.
When there is only one (unique)	The sun, the moon, the Earth
Before superlatives	She is the best student in class.
Before ordinal numbers	The first lesson, the second chapter
With geographical names (rivers, seas, mountain ranges)	The Nile, the Mediterranean, the Alps

3. Zero Article (No Article)

We do NOT use an article in these cases:

• Plural and uncountable nouns used in general: Dogs are loyal animals. | Water is essential for life.
• Proper nouns (names of people, countries, cities): Ahmed, Algeria, Paris
• Meals, sports, and languages: I have breakfast at 7. | He plays football. | She speaks Arabic.
