The importance of Words in The communications

Language is a tool for humans to communicate.
In ancient times, people communicate with the group by using the language.
According to a story in the Bible, humans use only one language, but because of human arrogance to match the greatness of God, the human tower of Babylon made high enough, but God became angry and destroyed the tower, so people scattered so fragmentary, so a lot of language emerges.
International language in the world is English, all the countries of the world to communicate using English. But in every country, is also developing a national language, which differs from one country to another country. For example the State language of Thailand, in contrast to Vietnamese, although these countries are geographically close together.
To be able to use the language well we need to learning word, then how to use word. Because of that, if we are wrong in taking the meaning of the word, so the communication will be disrupted.
The word is the smallest part of the letter, so the word can be described as an important part in making sentences. Because the word in a sentence composed would have a meaning that can be understood by others who are communicating, then help with word of great importance.
