Why we use india not the india
We cant use the article "the" before the countries like India,srilanka,pakistan,etc....but we still can use it before the countries like The USA,The philliphines,the netherlands,the united kingdom coz they are group of countries or group of islands ......India is a separate country,Usa is combined of north america and south america
Because before the name of a country,place or person,we do not use an article.
The name of a country,place or person are called proper nouns.And in front of a proper noun,we do not use an article.
Example:NOT the Tekun
Because Tekun is proper noun.
