Indefinite Articles
A and an are used to talk about any person or thing, not a particular one. They do not say exactly which person or thing we mean. These are called indefinite articles. For example, an orange is a fruit. An umbrella is a useful thing.
Use of 'a' or 'an'
We use:- A before words that start with a consonant sound; for example: a book, a cat, a doll, a fan, a girl, a hat, a jug, a kite, a lion, a man, a pen, a queen, a rat, a swan, a tiger, a van, a watch, a xylophone, a yak, a zebra.
- An before words that start with a vowel sound; for example: an apple, an elephant, an inkpot, an orange, an umbrella. But we say a university, a ewe, a unicorn, a European, a union, a one rupee.
More about articles
We say a one-eyed man, a useful thing, because these words begin with a consonant sound, even though they start with vowels. We say an hour, an honest man, an heir, an MA, an MBA, an X-mas tree, an S.C., an S.T., an F.I.R. because these words begin with a vowel sound even though their spellings start with h, m, x, s, or f, which are consonants.
Definite Article: The
"The" is used to talk about a particular person or thing. It is called the definite article. For example: The Rama, The Ganga, The Himalaya.
Indefinite Articles: a, an
When we mention a person or thing for the first time, we usually use a or an. But when we mention the same person or thing again, we use the definite article the. For example:
A boy once followed a path through a forest and came across a bridge over a river. He crossed the bridge over the river and left the path through the forest.
