Use Of The A And An Questions Medium
The article "an" is used before words that begin with a vowel sound. This includes words that start with the vowels A, E, I, O, and U, as well as words that start with a silent H. For example, "an apple," "an elephant," "an hour." However, it is important to note that the use of "an" is based on the sound of the word, not necessarily the letter it starts with. So, even if a word starts with a vowel, if it is pronounced with a consonant sound, the article "a" should be used instead. For example, "a university," "a one-dollar bill."
