I have a question about how different pronunciation of words and how this affects the use of indefinite articles.
My example is the technical abbreviation URL, meaning "uniform resource location". A common way to pronounce it is "you-are-ell", and to use the indefinite article a because of the consonant "y". -- Which is correct — a URL or an URL?
However, since it is an abbreviation, I have always pronounced it word-by-word "u-are-ell", and I have used the indefinite article an with this word.
I would like to extend this question to any word that have a different pronunciation as there are many different dialects.
Is it accepted to chose the indefinite article (a or an) based on how you pronounce a word?
