The key thing here is the word SOUND. It's all about vowel SOUNDS, not letters. For example, the letter 'u' sometimes has a vowel sound, for example an umbrella an urgent phone call But sometimes, the letter 'u' is pronounced with a consonant sound, like a 'y' a university a uniform It's the same with the letter 'h'. Sometimes it's a consonant sound: a hat a hamburger But sometimes it's silent, which makes the word begin with a vowel sound: an hour an honour Remember - it's all about the sound, not the spelling.

the a or an depends on the sound of the word. uniform is pronounced yuniform, so it's "a yuniform". honor has a silent h, so it's "an honor"

I hhope,,, these example would help you... AN ugly... AN umbrella... A university... A useful...
