Articulos a/an

AN

"AN" is used in front of words that begin with vowel sounds ("an equation" or "an element"), even if the word begins with a silent consonant ("an hour").

"AN" is used after a vowel (a, e, i, o, u).

Ejemplos:

A

When the word begins with a consonant you must use 'a'.

If you use words and phrases such as '' ball '', '' glass of water '' or '' cup of coffee '', then it would be "a ball", "a glass of water" and "a cup of coffee".

However, with this rule there is an exception. If you are using a word with a silent "h", such as "honorable" or "honest", then you have to use "an". Therefore, he would be "an honorable man" and "an honest mistake"
