-
- [Voiceover] So we've covered the
-
basic idea that divides the usage
-
of "the" from "a" and "an".
-
"The" is the definite article,
-
and "a" or "an" is the indefinite.
-
So when you're being non-specific
-
in language,
-
you would use
-
the indefinite article
-
as in,
-
"May I have
-
an orange?"
-
Cause it doesn't matter
-
which orange you're asking for,
-
you don't care,
-
it's any orange,
-
as opposed to if you wanted
-
the orange.
-
This usage is much more specific,
-
and it seems to indicate
that there is only
-
one orange.
-
You see the orange in
particular that you want,
-
you're identifying it,
-
you're asking for it.
-
That's what this definite usage is.
-
Something that's interesting about
-
the word "the"
-
is that it can be used for both singular
-
and plural nouns.
-
So it's both singular and plural.
-
So you could say
-
"May I have the orange?"
-
You could also say
-
"May I have the oranges?"
-
And "an" does not really allow this,
-
it is only singular.
-
So you can't say
-
"May I have an oranges?"
-
This is not standard.
-
What you'd probably say instead is
-
"May I have some oranges?"
-
So this is not standard,
-
does not work in standard
American English.
-
The other thing about "a" or "an"
-
is that it's "a" or "an".
-
The indefinite article changes
-
depending on the vowel sound
-
that comes after it.
-
So changes for vowel sounds.
-
Now what does that mean?
-
Well it means that if you know
-
that word that you're going to say next
-
like ah or ooh or eh or uh or ee,
-
then you're gonna change it to "an".
-
So it's the difference between saying
-
"A box,"
-
and
-
"An apple."
-
What we don't say
-
in standard American English
-
is "a apple."
-
It's not as easy on the mouth, frankly,
-
it takes a little bit more effort.
-
And any linguist will tell you
-
that the way languages develop
-
is that they were word laziness.
-
So we say "a box"
-
but we say "an apple."
-
Something a little weird though,
-
you want to make sure
-
that you're looking for vowel sounds
-
not just for vowels.
-
Because some vowels,
-
for example,
-
the letter U
-
don't always produce "ooh" sounds.
-
Sometimes if they're at
the beginning of a word,
-
like in word union,
-
so if you say "a union,"
-
that produces a "yuh" sound,
-
and "yuh" is technically
a consonant sound.
-
That's not a vowel.
-
But there are certainly cases like
-
"An underwater boat,"
-
where the letter U does produce
-
an "ooh" or an "uh" sound,
-
and that's a vowel.
-
So if you're gonna start the word
-
with a vowel sound,
-
what you wanna do is choose
-
"an" instead of "a"
-
but just be careful of
the letter U for example.
-
So to recap,
-
"the" is the definite article.
-
You can use it for both
singular and plural usage.
-
"May I have the orange?"
-
"May I have the oranges?"
-
"A" or "an" is indefinite
-
and it's only singular,
-
so you can say
-
"May I have an orange?"
-
or
-
"May I have some oranges?"
-
Before a vowel sound,
-
"a" changes to "an"
-
so you say "a box,"
-
but "an apple".
-
Not "a apple."
-
You say "a union,"
-
but "an underwater boat."
-
You can learn anything.
