FAQs
Why is "an good" grammatically incorrect?
The article "an" is used before words that begin with a vowel sound. Since "good" starts with a consonant sound (/g/), the correct article to use is "a". Therefore, the proper phrase is "a good".
What are some alternatives to the incorrect phrase "an good"?
The correct phrase is "a good". Depending on the context, you could also use alternatives such as "a fine" or "an excellent".
How do I remember when to use "a" versus "an"?
Use "a" before words that start with a consonant sound (e.g., a cat, a dog, a good book). Use "an" before words that start with a vowel sound (e.g., an apple, an egg, an excellent idea).
Is there ever a situation where "an" is used before the letter "h"?
Yes, "an" is used before words that begin with a silent "h", such as "an hour" or "an honest person". However, "good" does not have a silent "h", so the correct article is always "a good".
