📝 I. Introduction

Articles are small words that come before nouns. In English, there are two types of articles: indefinite (a, an) and definite (the). Choosing the right article depends on whether the noun is countable/uncountable, singular/plural, specific/general, or mentioned for the first or second time.

📚 II. The Indefinite Article: A / An

Rules:

• Use a before words that begin with a consonant sound: a book, a university, a European country, a one-way street
• Use an before words that begin with a vowel sound: an apple, an hour, an honest person, an umbrella, an elephant
• Only used with singular countable nouns: a car ✅, an idea ✅, a cars ❌, an informations ❌
• Used when mentioning something for the first time: I saw a dog in the street.
• Used with professions and nationalities: He is a doctor. She is an Algerian.
• Used in exclamations with what + countable noun: What a beautiful day!

Use “the” when:

• The noun is already known or mentioned before: I saw a dog. The dog was black.
• There is only one of something: the sun, the moon, the Earth, the president of Algeria
• It is clear from context: Please open the door. (the door of this room)
• With superlatives: the best, the tallest, the most important
• With ordinal numbers: the first lesson, the second chapter
