When to write “a” or “an” the rule is very simple it depends on the sound.

• A and consonant sound, if the following word starts with consonant sound, we write “a”: a game, a human
• AN and vowel sound, if the following word starts with a vowel sound, we write “an”: an umbrella, an apple
• Usually, we pronounce consonant letters with a consonant sound, and vowel letters with a vowel sound. The rule about a or an is still the same. We need to think about the sound, not the writing, for example: a European country (vowel letter but consonant sound), an hour (consonant letter but vowel sound)
