What is Communication ?

Meaning of Communication

Communication is a process which includes transmission of information, ideas, emotions, skills,  knowledge  by  using  symbols,  words,  gestures,  and  visuals and  so  on.  Thus,  the  act  of communication is referred to as ‘transmission’.

The word communication was originated from the Latin word ‘communis’ which means ‘common’. Communion, community, communism, commonality, communalism etc. are some related words having the same linguistic roots. Similarly, newer and newer terms are being coined as the concept of communication assumes importance day by day. Communication technology, communication media, communication age, communication management are just a few.
As the very term indicates, the ultimate aim of the communication process is to create commonness between communicator and receiver of the message. Through communication, both communicator and receiver enter into a mental agreement. Thus, they achieve their goal, which may be expression of an emotion or ransmission of an idea.

Transaction, interchange, interaction, dialogue, discussion, sharing, contact are some of the concepts that come up in our minds when we refer to ‘communication’.
