Definition of indefinite articles: 'a' and 'an' for first grade

📚 What are Indefinite Articles?

Indefinite articles are words we use before nouns (things) when we're talking about something in general, not something specific. The two indefinite articles in English are 'a' and 'an'. They tell us that we're talking about one of something, but it doesn't matter which one.

📜 History and Background

The words 'a' and 'an' come from the Old English word 'an', which meant 'one'. Over time, 'an' was used before words that started with a vowel sound, and 'a' was used before words that started with a consonant sound. This made it easier to say the words smoothly.

🔑 Key Principles

• 🗣️ Use 'a' before words that start with a consonant sound. For example, 'a cat', 'a dog', 'a book'.
• 👂 Use 'an' before words that start with a vowel sound (a, e, i, o, u). For example, 'an apple', 'an egg', 'an ice cream'.
• 💡 It's the sound that matters, not the letter. For example, 'an hour' (because 'hour' starts with a vowel sound even though it starts with the consonant 'h'), but 'a university' (because 'university' starts with a consonant sound even though it starts with the vowel 'u').
