As I’m sure you know, ‘a’ and ‘an’ are used before nouns, ‘an’ for those which start with a vowel (not actually the vowel, but a vowel sound) and ‘a’ for those which start with a consonant (the rest of the alphabet sounds). We all take this for granted, but why have 2 indefinite articles? It’s all about the smoothness of pronunciation.
Let’s look at what I’m talking about:
Say ‘a apple’, notice how it’s two distinct sounds with a small break between them, not very smooth. Now say, ‘an apple’, smooth as glass. The ‘an’ flows right into apple as one whole sound.
Now say, ‘an computer’, sounds a bit weird and feels a little strange on the tongue. By saying ‘an’, your tongue is left touching the roof of your mouth and has to totally change position to say the ‘c’ sound in computer.
Say, ‘a computer’, that’s better. When saying ‘a’ your mouth is basically in the default mode for speaking, mouth open in a natural position and your tongue at rest. It’s now easy to go into the ‘c’ sound in computer.
Say, ‘an umbrella’, all is well, it’s nice and smooth. Now say, ‘an university’, it feels and sounds quite a lot like saying ‘an computer’. The ‘uh’ sound in ‘umbrella’ is the actual vowel sound for the letter ‘u’, while the ‘u’ sound in ‘university’ is ‘yu’, a consonant sound.
So now we know why we use an ‘a’ before consonant sounds and ‘an’ before vowel sounds. But why is the difference between vowels themselves and vowel sounds important? Because in two cases, vowels don’t use a vowel sound and in one case, a consonant does.
When ‘o’ words begin with a ‘w’ sound like in the word ‘wow’:
a one-dollar bill
a once-in-a-lifetime opportunity
And more commonly, ‘u’ words that begin with the ‘yu’ sound:
a United Nations delegation
a unicorn
For consonants, in words that begin with the letter ‘h’ where the ‘h’ is silent, the word uses ‘an’:
an hour
an honour
but not an helicopter
So, that brings us to the video lesson. Nowhere do these pronunciation rules matter more than when pronouncing acronyms (if you’re not sure what an acronym is, that is also explained in the video lesson). The lesson also looks at another article rule regarding acronyms and the use of ‘the’.
