I think the poll should be changed/fixed whatever.
It only confuses new members because the wrong answer has more votes...
A university, A URL
I think it should be "an",because the URL is satrted with the letter U,but actually i see many people use "a",so now i am also confused.
The only true answer is "A URL".
I said it like a hundred times:
It does not matter whether a word starts with a vowel or not.
Please, read this:
The correct answer is a.
The letter u is a vowel but in the universal word it sounds as a consonant like when we say a university.
URL takes 'a' before it because it does not have a vowel sound. although it starts with 'u' a vowel, it doesn't have vowel sound.
And we say "an umbrella" and "an ultimatum" and while talking about "underproduction" I don't think that we use an or a for ex - The movie we were talking about is underproduction. or The new perfume is still under production.
