• What is communication?
• What is language?
• How communication need expands or changes languages

Communication simply means the transmission or exchange of information. Understanding is key in communication, although, not all that is communicated is usually understood by the listener as at the time of communication. The more the understanding of the listener(s), the more communication has happened.

Communication can be one-sided or two-sided: One sided communication is the kind that happens when a person communicates and the listener(s) hear and understand and do not communicate back. An example of this kind of communication exist in the military where a commander tells the soldiers what to do and they start doing it. Two sided communication happens when the persons or groups of persons speak and understand in turns. This kind of communication exist between business partners, and peers.

Humans differ from animals, or say, other animals on several lines and one of these lines is how they communicate. While animals, especially vertebrates, communicate by means of simple sounds and behaviours, humans communiate by means of behaviours and languages. Behaviour is also called body language for humans. While animals communicate to signal mates, defend themselves and their territory, and care for their young ones, humans communicate basically to give information, which may require an action or a reply.

“Humans communicate basically to inform”, notwithstanding, here are some of the whys in bits:

• Humans communicate to establish and maintain relationships and communities.
• Humans communicate to teach and to learn more about themselves and their environment.
• Humans communicate to exchange economic value. E.g. buying and selling is essentially possible because of communication.
• Humans communicate to express opinion or choice.

Language is simply a collection of words (written or spoken) and demonstrations used to communicate. Language is the major thing that differentiates humans communication from those of animals.

When a child is born, he starts to communicate by crying. Crying is not a language actually. It is a behaviour. When the child grows he starts to learn language from the society closest to him. Usually, it is the spoken form of the language he learns, since this is a more natural form of communication than writing or demonstration. After learning the basics of speaking, he learns to write and read the language symbols. This form is the written form. Demonstration is a rare form of a language, but happens to be the most important form of communication for deaf and dumbs. They demonstrate to communicate among themselves.

Behaviour is a very basic way of communication, but it is not really a language. Behaviours are not learned, they are natural. For example, a cattle does not learn to moo, neither does a dog learn to woof, so also, a child does not learn to cry or smile. These are natural. But languages are learned from the society. For example, a child who grows up in a deaf society may find it difficult to speak, but then be good at demonstrations since his society do not speak but rather demonstrates.

The primary reason for language is for communication. Without the need to communicate, humans would not need any language. Thus, when the need to communicate expands, languages expands to allow for better communication. For example, scientist invented a lot of words to describe different things they've discovered. Some words like Uranium, Polonium, etc., where invented to describe some chemical elements they discovered.

• Communication is the transfer or exchange of information.
• Animals communicate mostly through behaviours but humans communicate mostly through languages.
• Languages are collection of words (written or oral) and demonstrations used to communicate.
• Spoken form, written form, and demonstrative forms are the major forms of language.
• Demonstrative form differs from behaviours in that they are learned from society.
• The need for better communication has always been the reason for the expansion or modification of any language.
