Communication is the exchange of thoughts, messages, or information, as by speech, signals, writing, or behavior. Derived from the Latin word "communis", meaning to share. Communication requires a sender, a message, and a recipient, although the receiver need not be present or aware of the sender 's intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the message of the sender. The tool of communication is language. Language is a define as a system of sounds, words, patterns, etc used by human to communicate thoughts and feelings. (Hornby, 1974:699).

By language, people can express their mind and their wish and get more information or some knowledge from the world. Without language, people cannot communicate with others.
