We've all been taught in primary school how we're supposed to use 'an' instead of 'a' when we talk about an object whose name starts with a vowel, in its singular form.
-> An Apple
-> An Ostrich
-> An Elephant
But when we refer to one university, universe or even adjectives like useless, we use 'a' instead of 'an'.
-> A University
-> A Useless Boy
-> A Unique sight
Why is that so ? I get the fact that we use 'an' for words which start with consonants occasionally, for words like 'Hour','Honor', because the 'H' is silent. But what of the exceptions in the case of words starting with A,E,I,O,U ? Or is the just for certain words that start with 'U' ?
You might want to look at these two questions on English Language and Usage: Is it “a uniform” or “an uniform”?, When should I use “a” vs “an”?

5Read the accepted answer there: "If a word begins with a vowel sound, then the correct article is an; otherwise, if it begins with a consonantal sound, the correct article is a." A 'vowel' is a sound, not a letter, and the critical consideration is sound, not spelling. – StoneyB on hiatus – 2015-12-04T12:11:47.797
1Usage by native speakers changes over time (this should be remembered regarding every aspect of any language). In the past, an was used before words such as university and use, as well as hundred. At some point in the last generation or two the 'rules' (that is, usage) about this changed. – Alan Carmack – 2016-04-05T15:20:02.833
