discuss four uses of indefinite article​

Answer 1

Answer:

The indefinite article - Easy Learning Grammar

The indefinite article is a or an. The form an is used before a word that starts with a vowel sound.

a girl a cat

an eight-year-old girl an engineer

The indefinite article is used with singular countable nouns:

to refer to a person or a thing that you are mentioning for the first time in a conversation or a piece of writing.

A man was seen driving away in a black car.

to refer to a person or a thing which you do not want to be specific about.

I stopped off at a shop to buy a newspaper.

You go past a petrol station on the left, and then you’ll see our house on the right.

to refer to a person or a thing which you cannot be more specific about because there is not enough information.

A man called to see you this afternoon.

There was a telephone call for you a minute ago.

in definitions.

An octopus is a sea creature with eight tentacles.

when you refer to a person’s profession.

Her father is a dentist and her mother is a teacher.

to express a quantity, unless you wish to emphasize the number, when one must be used. The equivalent for plural nouns is some or no determiner at all. See Determiners.

Would you like a glass of wine?

There is only one glass of wine left in the bottle.

Guy has bought a skateboard.

It is the sound, not the spelling, that decides where an is used. For example, although unique begins with a vowel, the sound at the beginning resembles a y- sound.

an idiot an awful mistake

a unicorn a unique experience
