a hour vs an hour

The correct phrase is "an hour." The use of "an" before "hour" is necessary because the word "hour" begins with a vowel sound. This rule applies to all words that begin with a vowel sound, not just vowels themselves.

a hour

This is incorrect. The article "a" should not be used before the word "hour" because it begins with a vowel sound.

The correct phrase is "an hour" because the word "hour" starts with a vowel sound. Use "an" before words that begin with a vowel sound and "a" before words that begin with a consonant sound.

This is correct. The article "an" is used before the word "hour" because it begins with a vowel sound.
