Articles
These are modifiers used before nouns to indicate whether the speaker is referring to specific persons, places or things, or whether he is referring to them in a generic way.
A and AN
'A' and 'an' are called indefinite articles and indicate general reference. They are singular in form and cannot be used with plural nouns.
'The' is a definite article and indicates specific reference. It may be used with both singular and plural nouns.
Examples:
An illustration is placed on the board to make my point more understandable.
The illustration he presented is clear and understandable.
Use 'a' when the following noun begins with a consonant and 'an' with nouns that begin with a vowel (a, e, i, o, u)
Examples:
a book an egg
a pen an apple
a dog an igloo
But the difference between 'a' and 'an' is one of pronunciation, so we also use 'an' in front of a silent 'h' because judging only by sound, the word begins with the vowel that follows the 'h'.
Examples:
an honor
an herb
We also use 'a' before words that starts with a vowel when their pronunciation sounds like 'you'.
Examples:
a European
a unit
a university
If a noun is modified by an adjective, the choice between 'a' and 'an' depends on the initial sound of the adjective that immediately follows the article:
Examples:
a broken egg
an unusual problem
THE
The definite article 'the' is used with mass nouns for specific reference. It's not used with noncountable nouns referring to something general in use.
Examples:
(no article) Coffee is being brewed inside the cafeteria.
(no article) Japanese was his native language.
'The' is used with non-countable nouns that are made more specific by a limiting modifying phrase or clause.
Examples:
The coffee in my cup is too hot to drink
The Japanese he speaks is often heard in the country-side.
'The' is also used when a noun is referring to something that is unique.
Examples:
The Universe
The White House
The theory of relativity
