Overview of Indefinite Articles
Indefinite articles, specifically ‘a’ and ‘an’, are determiners used before singular, countable nouns. They indicate that the noun is general or unspecified, rather than a particular one.

Key Concepts
The choice between ‘a’ and ‘an’ depends on the sound that follows, not the letter itself:
- Use ‘a’ before words starting with a consonant sound.
- Use ‘an’ before words starting with a vowel sound.
Deep Dive: Sound vs. Letter
This rule can be tricky due to silent letters and exceptions:
- ‘a’ before consonant sounds: a book, a car, a university (university starts with a ‘y’ sound).
- ‘an’ before vowel sounds: an apple, an hour (h is silent), an honest person.
Consider the pronunciation:
a + consonant sound an + vowel sound
Applications
Indefinite articles are fundamental in English for:
- Introducing a noun for the first time: “I saw a dog.”
- Referring to a generic member of a class: “A doctor must be compassionate.”
- Indicating quantity: “I need an hour to finish this.”
Challenges & Misconceptions
Common errors include:
- Confusing the rule with the first letter of the word.
- Forgetting that indefinite articles are only used with singular, countable nouns.
The rule is about the initial sound, not the initial letter.
