Have you ever noticed how we refer to some countries as 'the [country name]' and others just as 'country name'?
How do you know when to use 'the' and when not to?
1) If the name of a country includes the words kingdom, states or republic we use
the when talking about that country.
the United Kingdom
the United States
the Republic of Ireland
the People's Republic of China
the Kingdom of Bhutan
2) If the name of a country is a plural name such as Netherlands or Philippines we use the.
