A or An?

Are indefinite forms of the

grammatical article in the

English language and can also

represent the number one .

Discrimination between: a and an

in

"A" goes before all words that begin with consonants.

For example:

With two exceptions:

Representing the number one:

In addition to serving as an

article, a and an are also

used as synonyms for the

number one, as in "make a

wish", "a hundred".

A or An?

A and an are also used

to express a proportional

relationship, such as: "a dollar

a day" or "$150 an ounce" or

"A Mars a day helps you work,

rest and play".

A or An?

Notes: The choice of article is

actually based upon the

phonetic (sound) quality of

the first letter in a word, not

on the orthographic (written)

representation of the letter.

A or An?

If the first letter makes

a vowel-type sound, you

use "an"; if the first letter

would makes a consonant-

type sound, you use "a."

A or An?

Now, with all these

rules in mind let’s

make and discuss a

practice exercise.

GOOD LUCK!
