1. Indefinite Articles: A & An
Used before singular, countable nouns when the listener or reader doesn't know the exact identity of the noun.
When to use "A"
Consonant SoundUse a before words that begin with a consonant sound (b, c, d, f, g, etc.).
• a book, a car, a dog
• a university (sounds like "y-uni...")
• a european country
When to use "An"
Vowel SoundUse an before words that begin with a vowel sound (a, e, i, o, u).
• an apple, an egg, an orange
• an hour (silent 'h', sounds like "our")
• an file (pronounced "ef-ile")
2. The Definite Article: The
Used before singular or plural nouns when both the speaker and listener know exactly which thing or person is being referred to.
Already Mentioned
