Which one is right

read the reasons below I hope 2 B clear

“an” is used if the singular countable noun begins with a vowel sound. If there are adjectives between the indefinite article and the noun, use the sound of the adjective nearest the article to determine whether “a” or “an” should be used. Most words that begin with a vowel sound also begin with a vowel letter. However, there are some exceptions, and those exceptions mostly occur with words that begin with “h” or “u”.

Examples: Ahmed had an egg for breakfast.

Nora wrote an opera.

Majed dreams of becoming an umpire someday.

I’d like to go to a university. *

Khalid would like to learn how to fly a helicopter.

He kept us waiting for over an hour. *

Mona sold a blue umbrella to Hind. *

Amal bought an ugly cat.*

· “University” begins with a vowel, but the first sound is pronounced /j/ as in “you”, which is a consonant sound, so “a” is used.

· “Hour” begins with a consonant, but the “h” is silent. The first sound that is pronounced is a vowel, so “an” is used.

· “Umbrella” begins with a vowel sound, but the adjective “blue” appears between “umbrella” and the indefinite article, and “blue” begins with a consonant sound. For that reason, “a” is used.

· “cat” begins with a consonant sound, but the adjective “ugly” appears between “cat” and the indefinite article, and “ugly” begins with a vowel sound. Therefore, “an” is used.
