The word ‘an’ is like a little helper that makes sentences sound smooth and nice. It is like wearing a special hat that only fits certain heads. You use ‘an’ before words that start with sounds like ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’. These are called vowel sounds. So, if you say ‘apple’, you say ‘an apple’ because ‘apple’ starts with an ‘a’ sound.

Imagine you have a basket with some colorful balls. There are red balls, blue balls, and green balls. When you pick a ball that is special, you say ‘an’. It’s like saying, ‘Look, I have an orange ball!’ because ‘orange’ starts with an ‘o’ sound, which is a vowel sound.

Think of ‘an’ as a friendly bridge that helps connect your words smoothly. Just like how a bridge helps you cross a river, ‘an’ helps your words flow better when you speak. If you see an elephant in a book, you say ‘an elephant’ because ‘elephant’ starts with an ‘e’ sound.

Remember, ‘an’ is always ready to help whenever you have a word that starts with a vowel sound. It’s like a magical key that unlocks the door to a smoother sentence!
