Explanation:
So in English, there are some exceptions to when you use "an" before words that start with vowels, and also some words that start with consonats and use "an." These might be tricky, but the best way to figure them out is to say them out loud. For example, if you said the first one out loud and you used "an" it would sound really weird. The best tip for trying to figure out grammar in English is to just sound the sentence or question out.
