The difference between 'a' and 'an'

A lot of us get to thinking that there exists this arbitrary rule within the English language that enforces people to say 'an' when the word following it begins with a vowel.

For instance, we say, "An artichoke" and, "An umbrella", but the gurus of language didn't intend us to do so simply because "we have to use 'an' when the next word starts with a vowel." That would be like saying, "The sun sets because it's night time."

The real reason the 'n' was added was because it can break the flow of a sentence when two vowel or consonant sounds are spoken without something to break them up. It has nothing to do with the letter itself, only the sound it makes within that word.

In most cases, we get it right.

Example 1a: "Next year, I'm going to make an Easter egg out of vegetables because I'm a rebel."

Example 1b: "Will it be a teeny tiny Easter egg, or a massive, fatty Easter egg comparable to the size of a fully grown elephant?"

However, because this rule has nothing to do with the consonant or the vowel itself, there are exceptions. When people misunderstand the rule, they are unable to adapt to these exceptions, and they begin to sound silly.

Example 1c (incorrect): " 'Fatty' was an euphemism, but I wouldn't mind trying a small Easter egg made out of vegetables."

Why is it wrong? Because it sounds silly.

Example 1c' (correct): " 'Fatty' was a euphemism. Having said that, anyone who dares to eat an Easter egg made out of vegetables will be shot and killed."

The word 'euphemism' begins with a consonant sound (you), not a vowel sound. Therefore, use 'a'. The rule was invented to make the flow of words easier, not harder, and that is entirely dependent on how the words sound. Make sense? Moving on.

Example 2: "Janet Bunnyhop's autobiography, Chocolate Heaven, Vegetable Hell, portrays the significance of Easter in an historical setting."

A teacher in high school taught me to write 'an' in a phrase such as the one above because the emphasis on the word 'historical' is placed on the second syllable - that is, historical - which is a vowel sound, and because the first letter - h - is almost silent. In other words, you will only have a case like this when the word begins with an 'h' and the emphasis of the word is placed on the second syllable. You wouldn't say, "I'm quite an happy man."

For a long while I thought it was a stupid exception, because 'a' carries the sentence just as well as 'an' does. So I did some research, and guess what? It doesn't even matter! You can ignore the rule in this case and do whatever you like. Perhaps your accent might dictate which word improves the outpouring of your speech, but feel free to decide which one you prefer.

Remember, it's the sound of the phrase that determines whether 'a' or 'an' is more appropriate. Something to note is that, because most people, such as the man at your next job interview, don't realise that the rule is based on the sound, they'll see 'an historical' (and other such phrases) and think it's wrong. Best to stick with 'a historical', at least in print.
