Indefinite articles - a and an (determiners)
A and an are the indefinite articles. They refer to something not specifically known to the person you are communicating with.
A and an are used beforenouns that introduce something or someone you have not mentioned before.
For example: | "I saw an elephant this morning."  “He visto un elefante esta mañana”
"I ate a banana for lunch." “Comíuna banana en el lunch”. |
A and an are also used when talking about your profession:-
For example: | "I am an English teacher." 
"I am a builder." |

Note! | You use a when the noun you arereferring to begins with a consonant (b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y or z), for example, "a city", "a factory", and "a hotel".You use an when the noun you are referring tobegins with a vowel (a, e, i, o, u)Pronunciation changes this rule. It's the sound that matters, not the spelling. 

If the next word begins with a consonant sound when we say it, for example,"university" then we use a. If the next word begins with a vowel sound when we say it, for example "hour" then we use an.We say "university" with a "y" sound at the beginning as though it were spelt"youniversity".
So, "a university" IS correct.We say "hour" with a silent h as though it were spelt "our".
So, "an hour" IS correct. |

Use a or an. Write the correct forms of the indefinite articles intothe gaps.
