How do you know when to use "a" and when to use "an" while speaking?
This rule is commonly misunderstood. Instead of looking at the initial letter of the word, you should focus on the initial sound. "A" precedes words beginning with a consonant sound while "an" precedes words beginning with a vowel sound. Examples: A dog. An apple. A unicorn. An honor.
