A, An, and The

A And An

A or An can precede only singular cunt nouns; they mean one. They can be used in general statement or to introduce a subject which has not been previously mentioned.

Use an before a word that starts with a vowel sound. If it does not start with a vowel sound, use a. For example:

• A man 
• An elephant 

But, look at this:

• A house 
• An hour 

The key word here is sound. It is not a question of whether the word starts with a vowel. It is a question of whether it starts with a vowel sound.

The

The is used to indicate something that we already know about or something that is common knowledge.

Examples:

• I have a cat. The cat is black.
• There is a book in my backpack. The book is very heavy.
• Do you know where I left the car keys? The listener knows which specific car keys you are talking about.
• Do you own a car? Is the car blue? You assume they do have a car after asking about it in the first sentence.
• Nobody lives on the Moon. The Moon is known to everyone.

IMPORTANT: You can use THE with both singular nouns and plural nouns.

Examples:

• I saw the bear in Yellowstone National Park.
• I saw the bears in Yellowstone National Park.
