When do I use 'a' and when do I use 'an'?

What is the difference between 'a' and 'an'?


When using the indefinite articles 'a' or 'an' it is customary to use 'a' before words beginning with consonants and 'an' before words beginning with vowels. In cases where the word following the article begins with the letter 'h', 'a' is typically used unless the 'h' is silent or not pronounced. For further information on using 'a' and 'an', please access the link to Oxford Reference below.
