• The English word communication has been evolved from two Latin words ‘Communis’ which means ‘Common’ or ‘Sharing’ and ‘Communicare’ which means ‘make something common’. With time the meaning of the word communication evolved and it has now become quite comprehensive.
• Primitive man used to communicate through signs and expressions. Later, people created their own local languages for communication which were called ‘dialects’. As civilization progressed people developed languages and ways to communicate. When science and technology emerged it brought several ways to communicate which we all see today.

Communication process:

• Communication is a two-way process. It deals with sending information from a source to a target.
• In this process, the sender collects the information in proper form and then sends it via. a proper medium. On the other hand the receiver of information interprets the information he receives and replies accordingly.
• One can exchange information, concepts, emotions, feelings, instructions, etc. to communicate with other.

We can classify communication in two types. They are:
1. Verbal communication:

• When an information or a message is transmitted using words of any language it is called verbal communication.
• Verbal communication can be either written or oral. In verbal communication one needs to select the words and their proper use in the sentence so as to communicate correctly. While creating a message for communication one should maintain the principle of ‘Keep It Short and Sweet (KISS)’ so that the message can be effective.

2. Non-verbal communication:

• Communication done without using words is called non-verbal communication.
• Non-verbal communication is done with the help of signs, physical expression, posture, facial and eye expressions. It can also be done with the help of music, singing, dancing, sculptures, painting, drawings, maps, paying tribute by firing cannons, blowing sirens and whistles, etc.
