The Definite Article: The

The definite article "The" is one of the most common words in the English language.

Main rule:

We put the in front of a noun to refer to people and things we assume our reader/listener knows about and can identify: The office is now closed.

We use it in front of:

singular and plural nouns: The book was cheap. The books were cheap.
the names of some countries, groups of islands, mountain ranges, oceans and rivers: the United Kingdom, the United States (of America), the Netherlands, the Himalayas, the English Channel, the Bahamas.
the names of newspapers, hotels, restaurants, theatres and museums: He always buys the Daily Mail. They stayed at the Savoy.
nouns like theatre, cinema, office when we think about them in general. I’m going to the cinema.
