I only do this as I like to learn new things myself and appreciate if people correct me.

You made a mistake in choosing to use an over a.

The way you can decide which one to use is by looking at the proceeding words first syllable sound. If it has a vowel sound you use an if it doesn’t, then you use a. It’s important to note it’s vowel sound and not just a vowel.

Examples:

• A teacher
• An apple
• A car
• An hour (note it starts with a vowel sound, but not a vowel)
• A US company
• An excellent teacher
