Hint: The above question asks us about the geographical use of the definite article “the” in front of the names of some countries but not with the others. When we feel the listener/reader knows exactly what we're talking about, we employ the definite article in front of a word.
Complete answer:
We do, however, use the definite article when referring to countries with names that incorporate words like kingdom, state, or republic.
Examples:
- The United States
- The United Kingdom
- The People’s Republic of China
"the" is also used with countries whose names are plural nouns:
- The Netherlands
- The Philippines
We say the United States, the United Kingdom, the Czech Republic, the West Indies, the Philippines, and the Netherlands because they are compound nouns with adjectives but not India, France, China, South Korea, Japan, Germany, or Indonesia.
Note: There are three standard rules to use article “the” before some countries:
- If the county name includes a common word, we use ‘The.' The United States of America, for example, includes the common noun ‘States' in its name, thus we must use ‘The.'
- If a nation name contains the word "of," the word "the" is used before it. Example: The Islamic Republic of Iran.
- If the country is an island country, we use the word ‘the.' Example: The Maldives.
