He is a university student why a use is use when u is a vowel so why we did not use an

Originally Answered: why we use 'a' before university why dont we use 'an'? That's because the use of 'a' and 'an' depends on the sound that begins the next word. "an" is used when the word begins with a vowel sound, and "a" is used when the word begins with a consonant sound.
