A Vs An By Sound Not SpellingSet 8
Frequently Asked Questions
When do you use "a" versus "an" in English?
The choice between "a" and "an" depends on the sound of the following word, not its spelling. Use "a" before words that start with a consonant sound and "an" before words that start with a vowel sound.
How do you determine if a word starts with a vowel sound?
A word starts with a vowel sound if it begins with the sounds of the vowels A, E, I, O, U, regardless of the actual first letter. For example, "hour" starts with a vowel sound, so "an hour" is correct.
What is the rule for using "a" before a consonant sound?
Use "a" before words that start with a consonant sound. For example, "a dog" is correct because "dog" starts with a consonant sound.
Why is "an" used before words starting with a vowel sound?
"An" is used before words starting with a vowel sound to maintain smooth pronunciation. For example, "an apple" is used because "a apple" would be awkward to say.
Can you give an example of an exception to the "a" and "an" rule?
An exception occurs with words that start with a silent "h," such as "hour." In this case, "an hour" is correct because the "h" is silent, and the word starts with a vowel sound.
